Backend session hijacking via session fixation

Published Sep 20, 2023 · Updated Sep 24, 2024

Session fixation in icmsdev iCMS 7.0.16 allows remote attackers to hijack authenticated website sessions via session cookies. The disclosure identifies hijacked cookies but does not name the session-handling locus or the incorrect operation on attacker-controlled input. Possession of a victim's session cookie is required and grants backend access without login, including deletion of files, comments, and users.
