Vulnerability from github – Published: 2023-10-13 00:30 – Updated: 2024-04-04 08:36

Details

On all Junos OS QFX5000 Series platforms, when pseudo-VTEP (Virtual Tunnel End Point) is configured under EVPN-VXLAN scenario, and specific DHCP packets are transmitted, DMA memory leak is observed. Continuous receipt of these specific DHCP packets will cause memory leak to reach 99% and then cause the protocols to stop working and traffic is impacted, leading to Denial of Service (DoS) condition. A manual reboot of the system recovers from the memory leak.

To confirm the memory leak, monitor for "sheaf:possible leak" and "vtep not found" messages in the logs.

This issue affects:

Juniper Networks Junos OS QFX5000 Series:

All versions prior to 20.4R3-S6;
21.1 versions prior to 21.1R3-S5;
21.2 versions prior to 21.2R3-S5;
21.3 versions prior to 21.3R3-S4;
21.4 versions prior to 21.4R3-S3;
22.1 versions prior to 22.1R3-S2;
22.2 versions prior to 22.2R2-S2, 22.2R3;
22.3 versions prior to 22.3R2-S1, 22.3R3;
22.4 versions prior to 22.4R1-S2, 22.4R2.

Title

Junos OS: QFX5000 Series: DMA memory leak is observed when specific DHCP packets are transmitted over pseudo-VTEP

Summary

An Improper Input Validation vulnerability in the Packet Forwarding Engine of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause memory leak, leading to Denial of Service (DoS). On all Junos OS QFX5000 Series platforms, when pseudo-VTEP (Virtual Tunnel End Point) is configured under EVPN-VXLAN scenario, and specific DHCP packets are transmitted, DMA memory leak is observed. Continuous receipt of these specific DHCP packets will cause memory leak to reach 99% and then cause the protocols to stop working and traffic is impacted, leading to Denial of Service (DoS) condition. A manual reboot of the system recovers from the memory leak. To confirm the memory leak, monitor for "sheaf:possible leak" and "vtep not found" messages in the logs. This issue affects: Juniper Networks Junos OS QFX5000 Series: * All versions prior to 20.4R3-S6; * 21.1 versions prior to 21.1R3-S5; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S4; * 21.4 versions prior to 21.4R3-S3; * 22.1 versions prior to 22.1R3-S2; * 22.2 versions prior to 22.2R2-S2, 22.2R3; * 22.3 versions prior to 22.3R2-S1, 22.3R3; * 22.4 versions prior to 22.4R1-S2, 22.4R2.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
