How to fix?

Upgrade edu.vt.middleware:vt-ldap to version 3.3.8 or higher.


edu.vt.middleware:vt-ldap is a Library for performing common LDAP operations.

Affected versions of this package are vulnerable to Improper Certificate Validation. It was discovered that the implementation used by the vtldap/ldaptive project to check that the server hostname matches the domain name in the subject's CN field was flawed. This can be exploited by a Man-in-the-middle (MITM) attack, where the attacker can spoof a valid certificate using a specially crafted subject.
