Vulnerability from github – Published: 2023-10-13 00:30 – Updated: 2024-04-04 08:37

Details

On all Junos MX Series with MPC1 - MPC9, LC480, LC2101, MX10003, and MX80, when Connectivity-Fault-Management (CFM) is enabled in a VPLS scenario, and a specific LDP related command is run, an FPC will crash and reboot. Continued execution of this specific LDP command can lead to sustained Denial of Service condition.

This issue affects:

Juniper Networks Junos OS on MX Series:

All versions prior to 20.4R3-S7;
21.1 versions prior to 21.1R3-S5;
21.2 versions prior to 21.2R3-S4;

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.
