CVE-2022-39387

CVE-2022-39387: XWiki OIDC Authenticator vulnerable to bypassing OpenID login by providing a custom provider

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.

Root Cause Analysis

The vulnerability stems from improper handling of request parameters in configuration loading. The key evidence comes from the patch which:

Introduces a SAFE_PROPERTIES whitelist (only allowing 'skipped')
Restricts getProperty() methods to only process request parameters for whitelisted properties
Modifies endpoint resolution to prevent direct parameter injection

The original vulnerable functions lacked these safeguards, allowing attackers to override OIDC endpoints, group mappings, and provider configurations through unvalidated request parameters. This directly enabled authentication bypass and privilege escalation as described in CVE-2022-39387.
