Editor-to-administrator account takeover via trusted user identifier
Published Jan 13, 2020 · Updated Aug 4, 2024
Privilege escalation in HashBrown CMS 1.3.3 and earlier allows remote authenticated users to take over administrator accounts. The postUser handler trusts an editor-controlled user identifier and passes submitted account properties to updateUserById, allowing another user's record to be targeted. Editor access is required; overwriting an administrator's password hash, salt, or token enables account takeover and broader account reconfiguration.
