Vulnerability Overview

The WP Cerber Security plugin for WordPress is vulnerable to security protection bypass in versions up to, and including 9.3.2, that makes user enumeration possible via the REST API. This is due the plugin not blocking access to the user endpoint when the plugin resides within a subdirectory. This can be used by unauthenticated attackers to gather information about users that can targeted in further attacks.

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.

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

Reaching this weakness in WP Cerber Security, Anti-spam & Malware Scan <= 9.3.2 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 WP Cerber Security, Anti-spam & Malware Scan the fix is 9.3.3: builds <= 9.3.2 are affected, anything from 9.3.3 onward is not.

Remediation

Update to version 9.3.3, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: WP Cerber Security, Anti-spam & Malware Scan 9.3.3 closes this, and updating the plugin is the step that ends it.
