CVE-2020-36658: High severity lemonldap::ng apache vulnerability

Published Jan 27, 2023
·
Updated

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.
