Vanilla Forums edit-profile page lets logged-in user change others’ settings

CVE-2012-4954 · published 13 years ago
Summary

If you run Vanilla Forums version before 2.1a32, a person who is already signed in can trick the system into thinking they are another user and alter that user’s profile information. This can happen when a network attacker intercepts and modifies the request data. Upgrade to version 2.1a32 or later to close the gap.
