Detailsinfo

A vulnerability classified as critical has been found in Apache OFBiz up to 24.09.7. Affected is the function checkExternalLoginKey of the component ExternalLoginKeysManager. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Authentication Bypass by Capture-replay in ExternalLoginKeysManager in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker who captures a live externalLoginKey value to obtain a complete, cookie-free, reusable session as the user who issued it, in every webapp that user can reach, because checkExternalLoginKey runs as a global preprocessor ahead of both the CSRF and authentication checks and accepts the key as a bearer credential that is never bound to a client, never expires, and is not invalidated after use, while the framework itself both appends live keys to every cross-webapp link it renders and, via WidgetWorker's unvalidated inter-app link target, lets an authenticated user's key be attached to an attacker-chosen absolute URL and delivered directly to the attacker's own server. Users are recommended to upgrade to version 24.09.08, which fixes this issue.
