Title
Junos OS and Junos OS Evolved: An attacker sending a specific genuine BGP packet causes a BGP reset
Summary
An Improper Input Validation vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker, sending a specific genuine BGP packet in an already established BGP session to reset only that session causing a Denial of Service (DoS).
An attacker repeatedly sending the packet will sustain the Denial of Service (DoS).This issue affects Junos OS:
* 25.2 versions before 25.2R2
This issue does not affect Junos OS versions before 25.2R1.
This issue affects Junos OS Evolved:
* 25.2-EVO versions before 25.2R2-EVO
This issue does not affect Junos OS Evolved versions before 25.2R1-EVO.
eBGP and iBGP are affected.

Title
Junos OS and Junos OS Evolved: When an unsigned Python op script configuration is present, a local low privileged user can compromise the system
Summary
An Execution with Unnecessary Privileges vulnerability in the User Interface (UI) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker to gain root privileges, thus compromising the system.
When a configuration that allows unsigned Python op scripts is present on the device, a non-root user is able to execute malicious op scripts as a root-equivalent user, leading to privilege escalation.
This issue affects Junos OS:
* All versions before 22.4R3-S7,
* from 23.2 before 23.2R2-S4,
* from 23.4 before 23.4R2-S6,
* from 24.2 before 24.2R1-S2, 24.2R2,
* from 24.4 before 24.4R1-S2, 24.4R2;
Junos OS Evolved:
* All versions before 22.4R3-S7-EVO,
* from 23.2 before 23.2R2-S4-EVO,
* from 23.4 before 23.4R2-S6-EVO,
* from 24.2 before 24.2R2-EVO,
* from 24.4 before 24.4R1-S1-EVO, 24.4R2-EVO.

Title
Junos OS and Junos OS Evolved: Execution of crafted CLI commands allows for arbitrary shell injection as root
Summary
An OS Command Injection vulnerability in the CLI processing of Juniper Networks Junos OS and Junos OS Evolved allows a local, high-privileged attacker executing specific, crafted CLI commands to inject arbitrary shell commands as root, leading to a complete compromise of the system.
Certain 'set system' commands, when executed with crafted arguments, are not properly sanitized, allowing for arbitrary shell injection. These shell commands are executed as root, potentially allowing for complete control of the vulnerable system.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* from 23.2 before 23.2R2-S5,
* from 23.4 before 23.4R2-S7,
* from 24.2 before 24.2R2-S2,
* from 24.4 before 24.4R2,
* from 25.2 before 25.2R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* from 23.2 before 23.2R2-S5-EVO,
* from 23.4 before 23.4R2-S7-EVO,
* from 24.2 before 24.2R2-S2-EVO,
* from 24.4 before 24.4R2-EVO,
* from 25.2 before 25.2R1-S1-EVO, 25.2R2-EVO.

Title
Junos OS Evolved: PTX Series: If SRTE tunnels provisioned via PCEP are present and specific gRPC queries are received evo-aftmand crashes
Summary
A Function Call With Incorrect Argument Type vulnerability in the sensor interface of Juniper Networks Junos OS Evolved on PTX Series allows a network-based, authenticated attacker with low privileges to cause a complete Denial of Service (DoS).
If colored SRTE policy tunnels are provisioned via PCEP, and gRPC is used to monitor traffic in these tunnels, evo-aftmand crashes and doesn't restart which leads to a complete and persistent service impact. The system has to be manually restarted to recover. The issue is seen only when the Originator ASN field in PCEP contains a value larger than 65,535 (32-bit ASN). The issue is not reproducible when SRTE policy tunnels are statically configured.
This issue affects Junos OS Evolved on PTX Series:
* all versions before 22.4R3-S9-EVO,
* 23.2 versions before 23.2R2-S6-EVO,
* 23.4 versions before 23.4R2-S7-EVO,
* 24.2 versions before 24.2R2-S4-EVO,
* 24.4 versions before 24.4R2-S2-EVO,
* 25.2 versions before 25.2R1-S2-EVO, 25.2R2-EVO.

Title
Junos OS and Junos OS Evolved: In an EVPN-MPLS scenario churn of ESI routes causes a memory leak in l2ald
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the Layer 2 Address Learning Daemon (l2ald) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a memory leak ultimately leading to a Denial of Service (DoS).
In an EVPN-MPLS scenario, routes learned from remote multi-homed Provider Edge (PE) devices are programmed as ESI routes. Due to a logic issue in the l2ald memory management, memory allocated for these routes is not released when there is churn for these routes. As a result, memory leaks in the l2ald process which will ultimately lead to a crash and restart of l2ald.
Use the following command to monitor the memory consumption by l2ald:
user@device> show system process extensive | match "PID|l2ald"
This issue affects:
Junos OS:
* all versions before 22.4R3-S5,
* 23.2 versions before 23.2R2-S3,
* 23.4 versions before 23.4R2-S4,
* 24.2 versions before 24.2R2;
Junos OS Evolved:
* all versions before 22.4R3-S5-EVO,
* 23.2 versions before 23.2R2-S3-EVO,
* 23.4 versions before 23.4R2-S4-EVO,
* 24.2 versions before 24.2R2-EVO.

Title
Junos OS and Junos OS Evolved: A high frequency of connecting and disconnecting NETCONF sessions causes management unavailability
Summary
An Incorrect Synchronization vulnerability in the management daemon (mgd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based attacker with low privileges to cause a complete Denial-of-Service (DoS) of the management plane.
When NETCONF sessions are quickly established and disconnected, a locking issue causes mgd processes to hang in an unusable state. When the maximum number of mgd processes has been reached, no new logins are possible. This leads to the inability to manage the device and requires a power-cycle to recover.
This issue can be monitored by checking for mgd processes in lockf state in the output of 'show system processes extensive':
user@host> show system processes extensive | match mgd
<pid> root 20 0 501M 4640K lockf 1 0:01 0.00% mgd
If the system still can be accessed (either via the CLI or as root, which might still be possible as last resort as this won't invoke mgd), mgd processes in this state can be killed with 'request system process terminate <PID>' from the CLI or with 'kill -9 <PID>' from the shell.
This issue affects:
Junos OS:
* 23.4 versions before 23.4R2-S4,
* 24.2 versions before 24.2R2-S1,
* 24.4 versions before 24.4R1-S3, 24.4R2;
This issue does not affect Junos OS versions before 23.4R1;
Junos OS Evolved:
* 23.4 versions before 23.4R2-S5-EVO,
* 24.2 versions before 24.2R2-S1-EVO,
* 24.4 versions before 24.4R1-S3-EVO, 24.4R2-EVO.
This issue does not affect Junos OS Evolved versions before 23.4R1-EVO;

Title
Junos OS Evolved: QFX5000 Series and PTX Series: An attacker sending crafted multicast packets will cause evo-aftmand / evo-pfemand to crash and restart
Summary
A Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in the advanced forwarding toolkit (evo-aftmand/evo-pfemand) of Juniper Networks Junos OS Evolved on PTX Series or QFX5000 Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).An attacker sending crafted multicast packets will cause line cards running evo-aftmand/evo-pfemand to crash and restart or non-line card devices to crash and restart. Continued receipt and processing of these packets will sustain the Denial of Service (DoS) condition.
This issue affects Junos OS Evolved PTX Series:
* All versions before 22.4R3-S8-EVO,
* from 23.2 before 23.2R2-S5-EVO,
* from 23.4 before 23.4R2-EVO,
* from 24.2 before 24.2R2-EVO,
* from 24.4 before 24.4R2-EVO.
This issue affects Junos OS Evolved on QFX5000 Series:
* 22.2-EVO version before 22.2R3-S7-EVO,
* 22.4-EVO version before 22.4R3-S7-EVO,
* 23.2-EVO versions before 23.2R2-S4-EVO,
* 23.4-EVO versions before 23.4R2-S5-EVO,
* 24.2-EVO versions before 24.2R2-S1-EVO,
* 24.4-EVO versions before 24.4R1-S3-EVO, 24.4R2-EVO.
This issue does not affect Junos OS Evolved on QFX5000 Series versions before: 21.2R2-S1-EVO, 21.2R3-EVO, 21.3R2-EVO, 21.4R1-EVO, and 22.1R1-EVO.

Title
Junos OS Evolved: PTX Series: A vulnerability allows a unauthenticated, network-based attacker to execute code as root
Summary
An Incorrect Permission Assignment for Critical Resource vulnerability in the On-Box Anomaly detection framework of Juniper Networks Junos OS Evolved on PTX Series allows an unauthenticated, network-based attacker to execute code as root.
The On-Box Anomaly detection framework should only be reachable by other internal processes over the internal routing instance, but not over an externally exposed port. With the ability to access and manipulate the service to execute code as root a remote attacker can take complete control of the device.
Please note that this service is enabled by default as no specific configuration is required.
This issue affects Junos OS Evolved on PTX Series:
* 25.4 versions before 25.4R1-S1-EVO, 25.4R2-EVO.
This issue does not affect Junos OS Evolved versions before 25.4R1-EVO.
This issue does not affect Junos OS.

Title
Junos OS and Junos OS Evolved: When telemetry collectors are frequently subscribing and unsubscribing to sensors chassisd or rpd will crash
Summary
A Use After Free vulnerability in the chassis daemon (chassisd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based attacker authenticated with low privileges to cause a Denial-of-Service (DoS).
When telemetry collectors are frequently subscribing and unsubscribing to sensors continuously over a long period of time, telemetry-capable processes like chassisd, rpd or mib2d will crash and restart, which - depending on the process - can cause a complete outage until the system has recovered.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5,
* 23.4 versions before 23.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S5-EVO,
* 23.4 versions before 23.4R2-EVO.

Title
Junos OS and Junos OS Evolved: Execution of crafted CLI commands allows for arbitrary shell injection as root
Summary
An OS Command Injection vulnerability in the CLI processing of Juniper Networks Junos OS and Junos OS Evolved allows a local, high-privileged attacker executing specific, crafted CLI commands to inject arbitrary shell commands as root, leading to a complete compromise of the system.
Certain 'set system' commands, when executed with crafted arguments, are not properly sanitized, allowing for arbitrary shell injection. These shell commands are executed as root, potentially allowing for complete control of the vulnerable system.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* from 23.2 before 23.2R2-S5,
* from 23.4 before 23.4R2-S7,
* from 24.2 before 24.2R2-S2,
* from 24.4 before 24.4R2,
* from 25.2 before 25.2R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* from 23.2 before 23.2R2-S5-EVO,
* from 23.4 before 23.4R2-S7-EVO,
* from 24.2 before 24.2R2-S2-EVO,
* from 24.4 before 24.4R2-EVO,
* from 25.2 before 25.2R1-S1-EVO, 25.2R2-EVO.

A Function Call With Incorrect Argument Type vulnerability in the sensor interface of Juniper Networks Junos OS Evolved on PTX Series allows a network-based, authenticated attacker with low privileges to cause a complete Denial of Service (DoS).
If colored SRTE policy tunnels are provisioned via PCEP, and gRPC is used to monitor traffic in these tunnels, evo-aftmand crashes and doesn't restart which leads to a complete and persistent service impact. The system has to be manually restarted to recover. The issue is seen only when the Originator ASN field in PCEP contains a value larger than 65,535 (32-bit ASN). The issue is not reproducible when SRTE policy tunnels are statically configured.
This issue affects Junos OS Evolved on PTX Series:
* all versions before 22.4R3-S9-EVO,
* 23.2 versions before 23.2R2-S6-EVO,
* 23.4 versions before 23.4R2-S7-EVO,
* 24.2 versions before 24.2R2-S4-EVO,
* 24.4 versions before 24.4R2-S2-EVO,
* 25.2 versions before 25.2R1-S2-EVO, 25.2R2-EVO.

Title
Junos OS and Junos OS Evolved: An attacker sending a specific genuine BGP packet causes a BGP reset
Summary
An Improper Input Validation vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker, sending a specific genuine BGP packet in an already established BGP session to reset only that session causing a Denial of Service (DoS).
An attacker repeatedly sending the packet will sustain the Denial of Service (DoS).This issue affects Junos OS:
* 25.2 versions before 25.2R2
This issue does not affect Junos OS versions before 25.2R1.
This issue affects Junos OS Evolved:
* 25.2-EVO versions before 25.2R2-EVO
This issue does not affect Junos OS Evolved versions before 25.2R1-EVO.
eBGP and iBGP are affected.

Title
Junos OS and Junos OS Evolved: In an EVPN-MPLS scenario churn of ESI routes causes a memory leak in l2ald
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the Layer 2 Address Learning Daemon (l2ald) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a memory leak ultimately leading to a Denial of Service (DoS).
In an EVPN-MPLS scenario, routes learned from remote multi-homed Provider Edge (PE) devices are programmed as ESI routes. Due to a logic issue in the l2ald memory management, memory allocated for these routes is not released when there is churn for these routes. As a result, memory leaks in the l2ald process which will ultimately lead to a crash and restart of l2ald.
Use the following command to monitor the memory consumption by l2ald:
user@device> show system process extensive | match "PID|l2ald"
This issue affects:
Junos OS:
* all versions before 22.4R3-S5,
* 23.2 versions before 23.2R2-S3,
* 23.4 versions before 23.4R2-S4,
* 24.2 versions before 24.2R2;
Junos OS Evolved:
* all versions before 22.4R3-S5-EVO,
* 23.2 versions before 23.2R2-S3-EVO,
* 23.4 versions before 23.4R2-S4-EVO,
* 24.2 versions before 24.2R2-EVO.

Title
Junos OS and Junos OS Evolved: A high frequency of connecting and disconnecting NETCONF sessions causes management unavailability
Summary
An Incorrect Synchronization vulnerability in the management daemon (mgd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based attacker with low privileges to cause a complete Denial-of-Service (DoS) of the management plane.
When NETCONF sessions are quickly established and disconnected, a locking issue causes mgd processes to hang in an unusable state. When the maximum number of mgd processes has been reached, no new logins are possible. This leads to the inability to manage the device and requires a power-cycle to recover.
This issue can be monitored by checking for mgd processes in lockf state in the output of 'show system processes extensive':
user@host> show system processes extensive | match mgd
<pid> root 20 0 501M 4640K lockf 1 0:01 0.00% mgd
If the system still can be accessed (either via the CLI or as root, which might still be possible as last resort as this won't invoke mgd), mgd processes in this state can be killed with 'request system process terminate <PID>' from the CLI or with 'kill -9 <PID>' from the shell.
This issue affects:
Junos OS:
* 23.4 versions before 23.4R2-S4,
* 24.2 versions before 24.2R2-S1,
* 24.4 versions before 24.4R1-S3, 24.4R2;
This issue does not affect Junos OS versions before 23.4R1;
Junos OS Evolved:
* 23.4 versions before 23.4R2-S5-EVO,
* 24.2 versions before 24.2R2-S1-EVO,
* 24.4 versions before 24.4R1-S3-EVO, 24.4R2-EVO.
This issue does not affect Junos OS Evolved versions before 23.4R1-EVO;

Junos OS Evolved: QFX5000 Series and PTX Series: An attacker sending crafted multicast packets will cause evo-aftmand / evo-pfemand to crash and restart
Summary
A Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in the advanced forwarding toolkit (evo-aftmand/evo-pfemand) of Juniper Networks Junos OS Evolved on PTX Series or QFX5000 Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).An attacker sending crafted multicast packets will cause line cards running evo-aftmand/evo-pfemand to crash and restart or non-line card devices to crash and restart. Continued receipt and processing of these packets will sustain the Denial of Service (DoS) condition.
This issue affects Junos OS Evolved PTX Series:
* All versions before 22.4R3-S8-EVO,
* from 23.2 before 23.2R2-S5-EVO,
* from 23.4 before 23.4R2-EVO,
* from 24.2 before 24.2R2-EVO,
* from 24.4 before 24.4R2-EVO.
This issue affects Junos OS Evolved on QFX5000 Series:
* 22.2-EVO version before 22.2R3-S7-EVO,
* 22.4-EVO version before 22.4R3-S7-EVO,
* 23.2-EVO versions before 23.2R2-S4-EVO,
* 23.4-EVO versions before 23.4R2-S5-EVO,
* 24.2-EVO versions before 24.2R2-S1-EVO,
* 24.4-EVO versions before 24.4R1-S3-EVO, 24.4R2-EVO.
This issue does not affect Junos OS Evolved on QFX5000 Series versions before: 21.2R2-S1-EVO, 21.2R3-EVO, 21.3R2-EVO, 21.4R1-EVO, and 22.1R1-EVO.

Title
Junos OS and Junos OS Evolved: When an unsigned Python op script configuration is present, a local low privileged user can compromise the system
Summary
An Execution with Unnecessary Privileges vulnerability in the User Interface (UI) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker to gain root privileges, thus compromising the system.
When a configuration that allows unsigned Python op scripts is present on the device, a non-root user is able to execute malicious op scripts as a root-equivalent user, leading to privilege escalation.
This issue affects Junos OS:
* All versions before 22.4R3-S7,
* from 23.2 before 23.2R2-S4,
* from 23.4 before 23.4R2-S6,
* from 24.2 before 24.2R1-S2, 24.2R2,
* from 24.4 before 24.4R1-S2, 24.4R2;
Junos OS Evolved:
* All versions before 22.4R3-S7-EVO,
* from 23.2 before 23.2R2-S4-EVO,
* from 23.4 before 23.4R2-S6-EVO,
* from 24.2 before 24.2R2-EVO,
* from 24.4 before 24.4R1-S1-EVO, 24.4R2-EVO.

Title
Junos OS Evolved: PTX Series: A vulnerability allows a unauthenticated, network-based attacker to execute code as root
Summary
An Incorrect Permission Assignment for Critical Resource vulnerability in the On-Box Anomaly detection framework of Juniper Networks Junos OS Evolved on PTX Series allows an unauthenticated, network-based attacker to execute code as root.
The On-Box Anomaly detection framework should only be reachable by other internal processes over the internal routing instance, but not over an externally exposed port. With the ability to access and manipulate the service to execute code as root a remote attacker can take complete control of the device.
Please note that this service is enabled by default as no specific configuration is required.
This issue affects Junos OS Evolved on PTX Series:
* 25.4 versions before 25.4R1-S1-EVO, 25.4R2-EVO.
This issue does not affect Junos OS Evolved versions before 25.4R1-EVO.
This issue does not affect Junos OS.

Title
Junos OS and Junos OS Evolved: When telemetry collectors are frequently subscribing and unsubscribing to sensors chassisd or rpd will crash
Summary
A Use After Free vulnerability in the chassis daemon (chassisd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based attacker authenticated with low privileges to cause a Denial-of-Service (DoS).
When telemetry collectors are frequently subscribing and unsubscribing to sensors continuously over a long period of time, telemetry-capable processes like chassisd, rpd or mib2d will crash and restart, which - depending on the process - can cause a complete outage until the system has recovered.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5,
* 23.4 versions before 23.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S5-EVO,
* 23.4 versions before 23.4R2-EVO.

Title
Junos OS Evolved: Flapping management interface causes MAC learning on label-switched interfaces to stop
Summary
An Incorrect Calculation vulnerability in the Layer 2 Control
Protocol
Daemon (l2cpd) of Juniper Networks Junos OS Evolved allows an unauthenticated network-adjacent attacker flapping the management interface to cause the learning of new MACs over label-switched interfaces (LSI) to stop while generating a flood of logs, resulting in high CPU usage.
When the issue is seen, the following log message will be generated:
op:1 flag:0x6 mac:xx:xx:xx:xx:xx:xx bd:2 ifl:13302 reason:0(REASON_NONE) i-op:6(INTRNL_OP_HW_FORCE_DELETE) status:10 lstatus:10 err:26(GETIFBD_VALIDATE_FAILED) err-reason 4(IFBD_VALIDATE_FAIL_EPOCH_MISMATCH) hw_wr:0x4 ctxsync:0 fwdsync:0 rtt-id:51 p_ifl:0 fwd_nh:0 svlbnh:0 event:- smask:0x100000000 dmask:0x0 mplsmask 0x1 act:0x5800 extf:0x0 pfe-id 0 hw-notif-ifl 13302 programmed-ifl 4294967295 pseudo-vtep underlay-ifl-idx 0 stack:GET_MAC, ALLOCATE_MAC, GET_IFL, GET_IFF, GET_IFBD, STOP,

FKIE_CVE-2026-21921
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 18:52
Severity
Summary
A Use After Free vulnerability in the chassis daemon (chassisd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based attacker authenticated with low privileges to cause a Denial-of-Service (DoS).
When telemetry collectors are frequently subscribing and unsubscribing to sensors continuously over a long period of time, telemetry-capable processes like chassisd, rpd or mib2d will crash and restart, which - depending on the process - can cause a complete outage until the system has recovered.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5,
* 23.4 versions before 23.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S5-EVO,
* 23.4 versions before 23.4R2-EVO.

FKIE_CVE-2026-21911
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 16:59
Severity
Summary
An Incorrect Calculation vulnerability in the Layer 2 Control
Protocol
Daemon (l2cpd) of Juniper Networks Junos OS Evolved allows an unauthenticated network-adjacent attacker flapping the management interface to cause the learning of new MACs over label-switched interfaces (LSI) to stop while generating a flood of logs, resulting in high CPU usage.
When the issue is seen, the following log message will be generated:
op:1 flag:0x6 mac:xx:xx:xx:xx:xx:xx bd:2 ifl:13302 reason:0(REASON_NONE) i-op:6(INTRNL_OP_HW_FORCE_DELETE) status:10 lstatus:10 err:26(GETIFBD_VALIDATE_FAILED) err-reason 4(IFBD_VALIDATE_FAIL_EPOCH_MISMATCH) hw_wr:0x4 ctxsync:0 fwdsync:0 rtt-id:51 p_ifl:0 fwd_nh:0 svlbnh:0 event:- smask:0x100000000 dmask:0x0 mplsmask 0x1 act:0x5800 extf:0x0 pfe-id 0 hw-notif-ifl 13302 programmed-ifl 4294967295 pseudo-vtep underlay-ifl-idx 0 stack:GET_MAC, ALLOCATE_MAC, GET_IFL, GET_IFF, GET_IFBD, STOP,
This issue affects Junos OS Evolved:
* all versions before 21.4R3-S7-EVO,
* from 22.2 before 22.2R3-S4-EVO,
* from 22.3 before 22.3R3-S3-EVO,

FKIE_CVE-2026-21909
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 19:40
Severity
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the routing protocol daemon (rpd) Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated attacker controlling an adjacent IS-IS neighbor to send a specific update packet causing a memory leak. Continued receipt and processing of these packets will exhaust all available memory, crashing rpd and creating a Denial of Service (DoS) condition.
Memory usage can be monitored through the use of the 'show task memory detail' command. For example:
user@junos> show task memory detail | match ted-infra
TED-INFRA-COOKIE 25 1072 28 1184 229
user@junos>
show task memory detail | match ted-infra
TED-INFRA-COOKIE 31 1360 34 1472 307
This issue affects:
Junos OS:
* from 23.2 before 23.2R2,
* from 23.4 before 23.4R1-S2, 23.4R2,
* from 24.1 before 24.1R2;
Junos OS Evolved:
* from 23.2 before 23.2R2-EVO,
* from 23.4 before 23.4R1-S2-EVO, 23.4R2-EVO,
* from 24.1 before 24.1R2-EVO.
This issue does not affect Junos OS versions before 23.2R1 or Junos OS Evolved versions before 23.2R1-EVO.

FKIE_CVE-2026-21908
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 19:40
Severity
Summary
A Use After Free vulnerability was identified in the 802.1X authentication daemon (dot1xd) of Juniper Networks Junos OS and Junos OS Evolved that could allow an authenticated, network-adjacent attacker flapping a port to crash the dot1xd process, leading to a Denial of Service (DoS), or potentially execute arbitrary code within the context of the process running as root.
The issue is specific to the processing of a change in authorization (CoA) when a port bounce occurs. A pointer is freed but was then referenced later in the same code path. Successful exploitation is outside the attacker's direct control due to the specific timing of the two events required to execute the vulnerable code path.
This issue affects systems with 802.1X authentication port-based network access control (PNAC) enabled.
This issue affects:
Junos OS:
* from 23.2R2-S1 before 23.2R2-S5,
* from 23.4R2 before 23.4R2-S6,
* from 24.2 before 24.2R2-S3,
* from 24.4 before 24.4R2-S1,
* from 25.2 before 25.2R1-S2, 25.2R2;
Junos OS Evolved:
* from 23.2R2-S1 before 23.2R2-S5-EVO,
* from 23.4R2 before 23.4R2-S6-EVO,
* from 24.2 before 24.2R2-S3-EVO,
* from 24.4 before 24.4R2-S1-EVO,
* from 25.2 before 25.2R1-S2-EVO, 25.2R2-EVO.

FKIE_CVE-2025-59959
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 19:38
Severity
Summary
An Untrusted Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, authenticated attacker with low privileges to cause a Denial-of-Service (DoS).
When the command 'show route < ( receive-protocol | advertising-protocol ) bgp > detail' is executed, and at least one of the routes in the intended output has specific attributes, this will cause an rpd crash and restart.
'show route ... extensive' is not affected.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5,
* 23.4 versions before 23.4R2-S5,
* 24.2 versions before 24.2R2-S2,
* 24.4 versions before 24.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S5-EVO,
* 23.4 versions before 23.4R2-S6-EVO,
* 24.2 versions before 24.2R2-S2-EVO,
* 24.4 versions before 24.4R2-EVO.

FKIE_CVE-2025-59960
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 19:39
Severity
Summary
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Juniper DHCP service (jdhcpd) of Juniper Networks Junos OS and Junos OS Evolved allows a DHCP client in one subnet to exhaust the address pools of other subnets, leading to a Denial of Service (DoS) on the downstream DHCP server.
By default, the DHCP relay agent inserts its own Option 82 information when forwarding client requests, optionally replacing any Option 82 information provided by the client. When a specific DHCP DISCOVER is received in 'forward-only' mode with Option 82, the device should drop the message unless 'trust-option82' is configured. Instead, the DHCP relay forwards these packets to the DHCP server unmodified, which uses up addresses in the DHCP server's address pool, ultimately leading to address pool exhaustion.
This issue affects Junos OS:
* all versions before 21.2R3-S10,
* from 21.4 before 21.4R3-S12,
* all versions of 22.2,
* from 22.4 before 22.4R3-S8,
* from 23.2 before 23.2R2-S5,
* from 23.4 before 23.4R2-S6,
* from 24.2 before 24.2R2-S2,
* from 24.4 before 24.4R2,
* from 25.2 before 25.2R1-S1, 25.2R2.
Junos OS Evolved:
* all versions before 21.4R3-S12-EVO,
* all versions of 22.2-EVO,
* from 22.4 before 22.4R3-S8-EVO,
* from 23.2 before 23.2R2-S5-EVO,
* from 23.4 before 23.4R2-S6-EVO,
* from 24.2 before 24.2R2-S2-EVO,
* from 24.4 before 24.4R2-EVO,
* from 25.2 before 25.2R1-S1-EVO, 25.2R2-EVO.

Cuando se recibe un DHCP DISCOVER espec\u00edfico en modo \u0027solo reenv\u00edo\u0027 con Opci\u00f3n 82, el dispositivo deber\u00eda descartar el mensaje a menos que \u0027trust-option82\u0027 est\u00e9 configurado.

FKIE_CVE-2025-60011
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 19:39
Severity
Summary
An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause an availability impact for downstream devices.
When an affected device receives a specific optional, transitive BGP attribute over an existing BGP session, it will be erroneously modified before propagation to peers. When the attribute is detected as malformed by the peers, these peers will most likely terminate the BGP sessions with the affected devices and thereby cause an availability impact due to the resulting routing churn.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5
* 23.4 versions before 23.4R2-S6,
* 24.2 versions before 24.2R2-S2,
* 24.4 versions before 24.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S5-EVO,
* 23.4 versions before 23.4R2-S6-EVO,
* 24.2 versions before 24.2R2-S2-EVO,
* 24.4 versions before 24.4R2-EVO.

FKIE_CVE-2025-59961
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 19:39
Severity
Summary
An Incorrect Permission Assignment for Critical Resource vulnerability in the Juniper DHCP daemon (jdhcpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged user to write to the Unix socket used to manage the jdhcpd process, resulting in complete control over the resource.
This vulnerability allows any low-privileged user logged into the system to connect to the Unix socket and issue commands to manage the DHCP service, in essence, taking administrative control of the local DHCP server or DHCP relay.
This issue affects:
Junos OS:
* all versions before 21.2R3-S10,
* all versions of 22.2,
* from 21.4 before 21.4R3-S12,
* from 22.4 before 22.4R3-S8,
* from 23.2 before 23.2R2-S5,
* from 23.4 before 23.4R2-S6,
* from 24.2 before 24.2R2-S2,
* from 24.4 before 24.4R2,
* from 25.2 before 25.2R1-S1, 25.2R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* from 23.2 before 23.2R2-S5-EVO,
* from 23.4 before 23.4R2-S6-EVO,
* from 24.2 before 24.2R2-S2-EVO,
* from 24.4 before 24.4R2-EVO,
* from 25.2 before 25.2R1-S1-EVO, 25.2R2-EVO.

FKIE_CVE-2025-60003
Vulnerability from fkie_nvd - Published: 2026-01-15 21:16 - Updated: 2026-01-23 19:39
Severity
Summary
A Buffer Over-read vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).
When an affected device receives a BGP update with a set of specific optional transitive attributes over an established peering session, rpd will crash and restart when attempting to advertise the received information to another peer.
This issue can only happen if one or both of the BGP peers of the receiving session are non-4-byte-AS capable as determined from the advertised capabilities during BGP session establishment. Junos OS and Junos OS Evolved default behavior is 4-byte-AS capable unless this has been specifically disabled by configuring:
[ protocols bgp ... disable-4byte-as ]
Established BGP sessions can be checked by executing:
show bgp neighbor <IP address> | match "4 byte AS"
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5,
* 23.4 versions before 23.4R2-S6,
* 24.2 versions before 24.2R2-S2,
* 24.4 versions before 24.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S5-EVO,
* 23.4 versions before 23.4R2-S6-EVO,
* 24.2 versions before 24.2R2-S2-EVO,
* 24.4 versions before 24.4R2-EVO.
