CVE-2022-27237Network attack vector

Browser script execution via unsafe redirect URI

Published Apr 21, 2022 · Updated Aug 3, 2024

Reflected XSS in NI Web Server in multiple NI products allows remote attackers to execute JavaScript through a crafted URL. The login/redirect.shtml page embeds the AUTH_REDIR_URI server variable into JavaScript without safe encoding, allowing attacker-controlled content to enter the browser's script context. Exploitation requires an enabled NI Web Server and a user who opens the crafted URL; successful code runs in that user's browser session.
