Title
Junos OS Evolved: PTX Series: If SRTE tunnels provisioned via PCEP are present and specific gRPC queries are received evo-aftmand crashes
Summary
A Function Call With Incorrect Argument Type vulnerability in the sensor interface of Juniper Networks Junos OS Evolved on PTX Series allows a network-based, authenticated attacker with low privileges to cause a complete Denial of Service (DoS).
If colored SRTE policy tunnels are provisioned via PCEP, and gRPC is used to monitor traffic in these tunnels, evo-aftmand crashes and doesn't restart which leads to a complete and persistent service impact. The system has to be manually restarted to recover. The issue is seen only when the Originator ASN field in PCEP contains a value larger than 65,535 (32-bit ASN). The issue is not reproducible when SRTE policy tunnels are statically configured.
This issue affects Junos OS Evolved on PTX Series:
* all versions before 22.4R3-S9-EVO,
* 23.2 versions before 23.2R2-S6-EVO,
* 23.4 versions before 23.4R2-S7-EVO,
* 24.2 versions before 24.2R2-S4-EVO,
* 24.4 versions before 24.4R2-S2-EVO,
* 25.2 versions before 25.2R1-S2-EVO, 25.2R2-EVO.

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.
