Privilege escalation via attacker-controlled back-end URL
Published May 1, 2025 · Updated May 2, 2025
Server-side request forgery in Sematell ReplyOne 7.4.3.0 allows remote authenticated users to obtain a back-end access token. The listPermissions GWT RPC accepts an attacker-controlled application-server URL and makes the web server request that host while forwarding its MM_SESSION cookie. A low-privileged account is required; the leaked cookie bypasses web-server checks, and response differences also expose internal TCP port status.
