CVE-2011-5250Network attack vector

Forced web actions via improperly implemented ChToken

Published Jan 8, 2020 · Updated Aug 7, 2024

Cross-site request forgery in Snare for Linux before 1.7.0 allows remote attackers to force authenticated users to perform web actions. The web interface improperly implements the ChToken request parameter, so crafted cross-site requests are accepted as authorized actions. Exploitation requires an authenticated user to visit attacker-controlled content, and the published disclosure does not specify which actions can be forced.
