CVE-2022-39387
XWiki OIDC Authenticator vulnerable to bypassing OpenID login by providing a custom provider
Impact
### Impact Even if a wiki has an OpenID provider configured through its xwiki.properties, it is possible to provide a third party provider by providing its details through request parameters. One can then bypass the XWiki authentication altogether by specifying its own provider through the oidc.endpoint.* request parameters (or by using an XWiki-based OpenID provider with oidc.xwikiprovider. With the same approach, one could also provide a specific group mapping through oidc.groups.mapping that would make his user automatically part of the XWikiAdminGroup ### Patches Patched in version 1.29.1. ### Workarounds There is no workaround, an upgrade of the authenticator is required. ### References https://jira.xwiki.org/browse/OIDC-118 ### For more information If you have any questions or comments about this advisory: * Open an issue in Jira XWiki * Email us at our security mailing list
