Vulnerability from github – Published: 2025-04-09 21:31 – Updated: 2025-04-15 21:31

Details

Continuous receipt of these packets will create a sustained Denial of Service (DoS) condition.

This issue affects Junos OS:

All versions before 21.4R3-S9,
from 22.2 before 22.2R3-S5,
from 22.4 before 22.4R3-S4,
from 23.2 before 23.2R2-S3,
from 23.4 before 23.4R2-S3,
from 24.2 before 24.2R1-S1, 24.2R2.

An indicator of compromise is to review the CPU % of the httpd process in the CLI: e.g. show system processes extensive | match httpd PID nobody 52 0 20M 191M select 2 0:01 80.00% httpd{httpd} <<<<< the percentage of httpd usage if high may be an indicator

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.
