Session cookie disclosure via unflagged error responses
Published Sep 21, 2022 · Updated May 28, 2025
Cookie protection failure in IKUS Software Rdiffweb before 2.4.6 allows attackers to obtain session cookies after invalid HTTPS requests. On error and redirect paths, the secure_headers hook runs too late to mark the session_id cookie Secure, so browsers can send it over HTTP. Exploitation requires a victim browser with an active session to make an affected request and expose the cookie across an unencrypted connection, enabling session hijacking.
