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 plugin for WordPress is vulnerable to LDAP Passback in versions up to, and including, 4.1.10. This is due to insufficient validation when changing the LDAP server. This makes it possible for authenticated attackers, with administrative access and above, to change the LDAP server and retrieve the credentials for the original LDAP server.
The Active Directory Integration / LDAP Integration plugin for WordPress is vulnerable to LDAP Injection in versions up to, and including, 4.1.5. This is due to insufficient escaping on the supplied username value. This makes it possible for unauthenticated attackers to extract potentially sensitive information from the LDAP directory.
