At a glance

CVE-2023-4506 is a high-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Active Directory Integration / LDAP Integration WordPress plugin, affecting versions <= 4.1.9. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 4.1.10; sites on affected versions should update now. Disclosed September 2023, reported by Pedro José Navas Pérez.

Vulnerability Overview

The Active Directory Integration / LDAP Integration plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 4.1.9 via a publicly accessible LDAP log buffer created when an administrator exports the logs. This makes it possible for unauthenticated attackers to visit the log URL and obtain the LDAP logs, especially in cases where directory indexing is enabled.

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 privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Active Directory Integration / LDAP Integration <= 4.1.9 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Active Directory Integration / LDAP Integration the fix is 4.1.10: builds <= 4.1.9 are affected, anything from 4.1.10 onward is not.

Remediation

Update to version 4.1.10, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Active Directory Integration / LDAP Integration 4.1.10 closes this, and updating the plugin is the step that ends it.
