Vulnerability from github – Published: 2024-07-11 18:31 – Updated: 2024-07-11 18:31

Details

Denial-of-Service (DoS).

If an attempt is made to access specific sensors on platforms not supporting these sensors, either via GRPC or netconf, chassisd will crash and restart leading to a restart of all FPCs and thereby a complete outage.

This issue affects Junos OS:

21.4 versions from 21.4R3 before 21.4R3-S5,
22.1 versions from 22.1R3 before 22.1R3-S4,
22.2 versions from 22.2R2 before 22.2R3,
22.3 versions from 22.3R1 before 22.3R2-S2, 22.3R3,
22.4 versions from 22.4R1 before 22.4R2.

This issue does not affect Junos OS versions earlier than 21.4.

Vulnerability from cvelistv5 – Published: 2024-07-11 16:04 – Updated: 2024-08-02 04:26

Title

Junos OS: Attempting to access specific sensors on platforms not supporting these will lead to a chassisd crash

Summary

An Improper Check for Unusual or Exceptional Conditions vulnerability in the chassis management daemon (chassisd) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). If an attempt is made to access specific sensors on platforms not supporting these sensors, either via GRPC or netconf, chassisd will crash and restart leading to a restart of all FPCs and thereby a complete outage. This issue affects Junos OS: * 21.4 versions from 21.4R3 before 21.4R3-S5, * 22.1 versions from 22.1R3 before 22.1R3-S4, * 22.2 versions from 22.2R2 before 22.2R3, * 22.3 versions from 22.3R1 before 22.3R2-S2, 22.3R3, * 22.4 versions from 22.4R1 before 22.4R2. This issue does not affect Junos OS versions earlier than 21.4.

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.
