Vulnerability from github – Published: 2024-07-11 18:31 – Updated: 2025-04-11 15:32

Details

A Missing Release of Memory after Effective Lifetime vulnerability in Juniper Networks Junos OS on MX Series allows an unauthenticated adjacent attacker to cause a Denial-of-Service (DoS).

In a subscriber management scenario continuous subscriber logins will trigger a memory leak and eventually lead to an FPC crash and restart.

This issue affects Junos OS on MX Series:

All version before 21.2R3-S6,
21.4 versions before 21.4R3-S6,
22.1 versions before 22.1R3-S5,
22.2 versions before 22.2R3-S3,
22.3 versions before 22.3R3-S2,
22.4 versions before 22.4R3,
23.2 versions before 23.2R2.

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.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
