Name of the Vulnerable Software and Affected Versions SAML Single Sign On versions prior to 5.4.7
Description The plugin fails to verify the signature of a SAML response before storing the included certificate. An administrator can then promote this stored certificate to the site's trusted signing certificate via a one-click control. This allows unauthenticated attackers to establish trust for their own certificate and authenticate as any user, including those with administrator privileges.
Recommendations Update to version 5.4.7 or later.
