A vulnerability was found in XWiki Platform Web Templates (Content Management System). It has been classified as critical. Affected is some unknown processing of the component Email Verification Handler. The manipulation with an unknown input leads to a authentication bypass vulnerability. CWE is classifying the issue as CWE-288. A product requires authentication, but the product has an alternate path or channel that does not require authentication. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

XWiki Platform Web Templates are templates for XWiki Platform, a generic wiki platform. By passing a template of the distribution wizard to the xpart template, user accounts can be created even when user registration is disabled. This also circumvents any email verification. Before versions 14.2 and 13.10.4, this can also be exploited on a private wiki, thus potentially giving the attacker access to the wiki. Depending on the configured default rights of users, this could also give attackers write access to an otherwise read-only public wiki. Users can also be created when an external authentication system like LDAP is configured, but authentication fails unless the authentication system supports a bypass/local accounts are enabled in addition to the external authentication system. This issue has been patched in XWiki 13.10.5 and 14.3RC1. As a workaround, one may replace `xpart.vm`, the entry point for this attack, by a patched version from the patch without updating XWiki.

The weakness was presented 09/09/2022 as GHSA-h5j3-5x63-p8jv. The advisory is available at github.com. This vulnerability is traded as CVE-2022-36093 since 07/15/2022. The technical details are unknown and an exploit is not available.

Upgrading to version 13.10.5 or 14.3RC1 eliminates this vulnerability. Applying the patch 70c64c23f4404f33289458df2a08f7c4be022755 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
