In Apache::Session::LDAP before 0.5, validity of the X.509 certificate is not checked by default when connecting to remote LDAP backends, because the default configuration of the Net::LDAPS module for Perl is used. NOTE: this can, for example, be fixed in conjunction with the CVE-2020-16093 fix.

Weakness

The product does not validate, or incorrectly validates, a certificate.
