Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
The impacted products, when configured to use SSO, are affected by an improper authentication vulnerability. This vulnerability allows the application to accept manual entry of any active directory (AD) account provisioned in the application without supplying a password, resulting in access to the application as the supplied AD account, with all associated privileges.
