What is CVE-2020-16093?

In versions of LemonLDAP::NG up to 2.0.8, an important security concern exists where the validity of X.509 certificates is not verified by default during connections to remote LDAP backends. This oversight arises from the use of default settings in the Perl Net::LDAPS module, posing potential risks for systems relying on secure LDAP communications. Administrators are encouraged to reconfigure their setups to enforce certificate validation and mitigate associated security threats.
