CVE-2025-29691Public exploitNetwork attack vector

Script execution via unneutralized login username

Published May 14, 2025 · Updated May 15, 2025

Cross-site scripting in OA System before 2025.01.01 allows remote attackers to execute web scripts through the login userName parameter. The login controller places the crafted userName value into generated page output without neutralizing executable HTML or script content. No authentication is required, but a user must render the tainted response; execution is limited to that user's browser context.
