Name of the Vulnerable Software and Affected Versions Apereo Central Authentication Service (CAS) Server versions prior to 3.5.3

Description The issue allows remote attackers to conduct LDAP injection attacks via a crafted username, potentially bypassing LDAP authentication. This can be achieved by using a wildcard and a valid password.

Recommendations For versions prior to 3.5.3, update to version 3.5.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the LDAP authentication mechanism until the update is applied.
