CVE-2023-6790Network attack vector

Administrator-context JavaScript execution via crafted link

Published Dec 13, 2023 · Updated Aug 2, 2024

DOM-based XSS in Palo Alto Networks PAN-OS allows remote attackers to run JavaScript in an administrator's browser via a crafted link. The vendor has not disclosed the web-interface DOM source, sink, or missing neutralization step that processes attacker-controlled URL data. Exploitation requires an administrator to open the link, and the payload then executes with that administrator's web-interface context.
