Victim-side script execution via unencoded langcode

Published Mar 24, 2025 · Updated Mar 25, 2025

Reflected XSS in Yonyou UFIDA NC 5.0 allows remote attackers to execute script in a victim's browser via a crafted langcode value. The /help/top.jsp page reads langcode from the request and inserts it into link and image attributes without context-appropriate encoding. Exploitation requires a victim to open the crafted URL and confines script execution to the affected page's browser context.
