At a glance

CVE-2024-11194 is a high-severity Missing Authorization vulnerability in the Classified Listing WordPress plugin, affecting versions <= 3.1.15.1. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.1.16; sites on affected versions should update now. Disclosed November 2024, reported by vgo0.

Vulnerability Overview

The Classified Listing – Classified ads & Business Directory Plugin plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a misconfigured check on the 'rtcl_import_settings' function in all versions up to, and including, 3.1.15.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update limited arbitrary options on the WordPress site. This can be leveraged to update the Subscriber role with Administrator-level capabilities to gain administrative user access to a vulnerable site. The vulnerability is limited in that the option updated must have a value that is an array.

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, integrity, availability — full site compromise territory.

CWE-862: Missing Authorization

Classified Listing <= 3.1.15.1 carries this weakness at rtcl_import_settings, and reaching it takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Classified Listing the fix is 3.1.16: builds <= 3.1.15.1 are affected, anything from 3.1.16 onward is not.

Remediation

Update to version 3.1.16, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Classified Listing 3.1.16 closes this, and updating the plugin is the step that ends it.
