Summary

A predictable temporary filename vulnerability in PAN-OS allows local privilege escalation. This issue allows a local attacker who bypassed the restricted shell to execute commands as a low privileged user and gain root access on the PAN-OS hardware or virtual appliance. This issue affects only PAN-OS 8.1 versions earlier than PAN-OS 8.1.13. This issue does not affect PAN-OS 7.1, PAN-OS 9.0, or later PAN-OS versions.

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.
