CVE-2023-49111Public exploitNetwork attack vector

Credential theft via reflected login-page script injection

Published Jun 20, 2024 · Updated Nov 4, 2025

Reflected XSS in Kiuwan Code Security before master.1808.p685.q13371 allows remote attackers to run script through a crafted login link. The login.html handler inserts the message request parameter directly into a JavaScript block without safe encoding. Execution requires victim interaction and an SSO domain ID cached in browser local storage, enabling attacker-controlled script to capture entered AD credentials.
