CVE-2023-6789 PAN-OS: Stored Cross-Site Scripting (XSS) Vulnerability in the Web Interface
Description
A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a malicious authenticated read-write administrator to store a JavaScript payload using the web interface. Then, when viewed by a properly authenticated administrator, the JavaScript payload executes and disguises all associated actions as performed by that unsuspecting authenticated administrator.
