At a glance

CVE-2023-3447 is a high-severity Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection') vulnerability in the Active Directory Integration / LDAP Integration WordPress plugin, affecting versions <= 4.1.5. It carries a CVSS score of 7.6 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 4.1.6; sites on affected versions should update now. Disclosed June 2023, reported by Luca Greeb.

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

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

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.

Remediation

Update to version 4.1.6, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Active Directory Integration / LDAP Integration 4.1.6 closes this, and updating the plugin is the step that ends it.
