Vulnerability from cvelistv5 – Published: 2021-06-04 11:39 – Updated: 2024-08-03 17:01
VLAI
Summary
A flaw was found in tpm2-tools in versions before 5.1.1 and before 4.3.2. tpm2_import used a fixed AES key for the inner wrapper, potentially allowing a MITM attacker to unwrap the inner portion and reveal the key being imported. The highest threat from this vulnerability is to data confidentiality.
Severity
No CVSS data available.

Title
UUPSUpgradeable vulnerability in OpenZeppelin Contracts
Summary
OpenZeppelin Contracts is a library for smart contract development. In affected versions upgradeable contracts using `UUPSUpgradeable` may be vulnerable to an attack affecting uninitialized implementation contracts. A fix is included in version 4.3.2 of `@openzeppelin/contracts` and `@openzeppelin/contracts-upgradeable`. For users unable to upgrade; initialize implementation contracts using `UUPSUpgradeable` by invoking the initializer function (usually called `initialize`). An example is provided [in the forum](https://forum.openzeppelin.com/t/security-advisory-initialize-uups-implementation-contracts/15301).

CVE-2022-0847 (GCVE-0-2022-0847)
Vulnerability from cvelistv5 – Published: 2022-03-07 00:00 – Updated: 2025-10-21 23:15

Summary
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.

Junos OS Evolved: Telnet service may be enabled when it is expected to be disabled.
Summary
An Improper Initialization vulnerability in Juniper Networks Junos OS Evolved may cause a commit operation for disabling the telnet service to not take effect as expected, resulting in the telnet service staying enabled. When it is not intended to be operating on the device, an administrator can issue the following command to verify whether telnet is operating in the background: user@device > show system connections | grep :23 tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN 20879/xinetd This issue affects: Juniper Networks Junos OS Evolved All versions prior to 20.4R2-S2-EVO; 21.1 version 21.1R1-EVO and later versions; 21.2 versions prior to 21.2R2-EVO.

Title
Junos OS and Junos OS Evolved: OSPFv3 session might go into INIT state upon receipt of multiple crafted packets from a trusted neighbor device.
Summary
An Improper Initialization vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker who sends specific packets in certain orders and at specific timings to force OSPFv3 to unexpectedly enter graceful-restart (GR helper mode) even though there is not any Grace-LSA received in OSPFv3 causing a Denial of Service (DoS). Unexpectedly entering GR helper mode might cause the OSPFv3 neighbor adjacency formed on this interface to be stuck in the "INIT" state which can be observed by issuing the following command: user@device> show ospf3 neighbor ID Interface State xx.xx.xx.xx ae100.0 Init <<<<<<<<<< An indicator of compromise can be seen in log files when traceoptions for OSPFv3 are enabled before the issue occurs. These logfile messages are as follows: OSPF restart signaling: Received hello with LR bit set from nbr ip=xx::xx id=xx.xx.xx.xx. Set oob-resync capabilty 1. OSPF Restart Signaling: Start helper mode for nbr ip xx::xx id xx.xx.xx.xx OSPF restart signaling: abort helper mode for nbr ip=xx::xx id=xx.xx.xx.xx OSPF neighbor xx::xx (realm ipv6-unicast <interface.unit> area xx.xx.xx.xx) state changed from Full to Init due to 1WayRcvd (event reason: neighbor is in one-way mode) (nbr helped: 0) This issue affects: Juniper Networks Junos OS. 15.1 versions prior to 15.1R7-S11; 18.3 versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S10; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S7, 19.2R3-S4; 19.3 versions prior to 19.3R2-S7, 19.3R3-S4; 19.4 versions prior to 19.4R3-S6; 20.1 versions prior to 20.1R3-S1; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R2-S2, 20.4R3; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2. This issue does not affect any version of Juniper Networks Junos OS 12.3. This issue affects Juniper Networks Junos OS Evolved all versions prior to 21.2R2-EVO.

Title
Junos OS: EX4650 Series: Certain traffic received by the Junos OS device on the management interface may be forwarded to egress interfaces instead of discarded
Summary
Due to an Improper Initialization vulnerability in Juniper Networks Junos OS on EX4650 devices, packets received on the management interface (em0) but not destined to the device, may be improperly forwarded to an egress interface, instead of being discarded. Such traffic being sent by a client may appear genuine, but is non-standard in nature and should be considered as potentially malicious. This issue affects: Juniper Networks Junos OS on EX4650 Series: All versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R2; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R1.

Mitigation ID: MIT-3
Phase: Requirements
Strategy: Language Selection
Description:
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable's type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
Mitigation
Phase: Architecture and Design
Description:
- Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Phase: Implementation
Description:
- Explicitly initialize all your variables and other data stores, either during declaration or just before the first usage.
Mitigation
Phase: Implementation
Description:
- Pay close attention to complex conditionals that affect initialization, since some conditions might not perform the initialization.
Mitigation
Phase: Implementation
Description:
- Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Phase: Build and Compilation
Description:

CAPEC-26: Leveraging Race Conditions
The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.
CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
