- GHSA-954f-xw44-56r2Authentication cache in Active Directory Jenkins Plugin allows logging in with any password2022-05-24ghsa · osvUS
Jenkins Active Directory Plugin implements two separate modes: Integration with ADSI on Windows, and an OS agnostic LDAP-based mode. Optionally, to reduce lookup time, a cache can be configured to remember user lookups and user authentications. In Active Directory Plugin prior to 2.20 and 2.16.1, when run in Windows/ADSI mode, the provided password was not used when looking up an applicable cache entry. This allows attackers to log in as any user using any password while a successful authentication of that user is still in the cache. As a workaround for this issue, the cache can be disabled. Active Directory Plugin 2.20 and 2.16.1 includes the provided password in cache entry lookup. Additionally, the Java system property `hudson.plugins.active_directory.CacheUtil.noCacheAuth` can be set to `true` to no longer cache user authentications.
