Stored XSS via unsanitized administrator parameters
Published Oct 22, 2021 · Updated Aug 3, 2024
Stored XSS in McAfee ePolicy Orchestrator before 5.10 Update 11 allows remote authenticated users to inject script through parameters. Multiple administrative input parameters store entries without correctly sanitizing embedded HTML or script before later rendering. Administrator privileges are required to plant the payload, and another user's interaction executes it in the console, enabling data access or actions in that user's session.
