Authenticated JavaScript execution via reflected skin input
Published Sep 23, 2024 · Updated Jul 5, 2026
Reflected XSS in Temenos Transact T24 Browser R19.40 allows remote authenticated users to execute JavaScript via the skin parameter. The about.jsp and genrequest.jsp handlers return attacker-controlled skin input without context-appropriate output encoding. Exploitation requires another user to open the crafted request, and execution remains within that victim's authenticated browser session.
