CVE-2025-36239Network attack vector

Credential disclosure via unsanitized expired-password URL parameter

Published Sep 27, 2025 · Updated Sep 27, 2025

Cross-site scripting in the IBM TS4500 Tape Library Web UI 1.11.0.0 and 2.11.0.0 allows remote attackers to run JavaScript. The expired-password page writes a URL parameter directly into HTML without sanitization or context-appropriate encoding. Exploitation requires a trusted-session user to open the crafted page, and script execution can disclose credentials or alter only that page in the user's session.
