Technical details

The AdminImportExport::TemplateDelete action in OTRS fails to validate the ChallengeToken, allowing CSRF attacks. An unauthenticated remote attacker can craft a malicious cross-site request that, when executed in the browser of an authenticated administrator, deletes administrative Import/Export templates without authorization. The vulnerability requires user interaction (the administrator must visit a malicious site while logged in) but requires no authentication from the attacker.
