Vulnerability Overview

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 attackers, with an existing account on a vulnerable WordPress instance, to extract potentially sensitive information from the LDAP directory.

Technical Analysis

REMEDIATION: Update to version 4.1.6, or a newer patched version --- IDENTIFIER: CWE-90 (Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')) The product constructs all or part of an LDAP query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended LDAP query when it is sent to a downstream component.
