Title
PAN-OS: Reflected Cross-Site Scripting (XSS) in Web Interface
Summary
A reflected cross-site scripting (XSS) vulnerability in the Palo Alto Network PAN-OS web interface enables an authenticated network-based attacker to mislead another authenticated PAN-OS administrator to click on a specially crafted link that performs arbitrary actions in the PAN-OS web interface as the targeted authenticated administrator. This issue impacts: PAN-OS 8.1 versions earlier than 8.1.20; PAN-OS 9.0 versions earlier than 9.0.14; PAN-OS 9.1 versions earlier than 9.1.10; PAN-OS 10.0 versions earlier than 10.0.2. This issue does not affect Prisma Access.

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.
