The Active Directory Integration / LDAP Integration WordPress plugin before 4.1.10 stores sensitive LDAP logs in a buffer file when an administrator wants to export said logs. Unfortunately, this log file is never removed, and remains accessible to any users knowing the URL to do so.
The Active Directory Integration / LDAP Integration WordPress plugin before 4.1.1 does not have proper authorization or nonce values for some POST requests, leading to unauthenticated data disclosure.
The 'LDAP Integration with Active Directory and OpenLDAP - NTLM & Kerberos Login' extension is vulnerable to LDAP Injection since is not properly sanitizing the 'username' POST parameter. An attacker can manipulate this paramter to dump arbitrary contents form the LDAP Database.
