At a glance

CVE-2023-6584 is a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the JobSearch WP Job Board WordPress plugin, affecting versions <= 2.3.3. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.3.4; sites on affected versions should update now. Disclosed November 2023, reported by Marc-Alexandre Montpas.

Vulnerability Overview

The JobSearch WP Job Board plugin for WordPress is vulnerable to authenticated bypass in all versions up to, and including, 2.3.3. This is due to the plugin not properly validating a users identity through the jobsearch_facebook_get_soc_login_url action. This makes it possible for unauthenticated attackers to log in as any user, including administrators, as long as they have access to the email address.

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, integrity, availability — full site compromise territory.

CWE-288: Authentication Bypass Using an Alternate Path or Channel

Reaching this weakness in JobSearch WP Job Board <= 2.3.3 takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.

The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. For JobSearch WP Job Board the fix is 2.3.4: builds <= 2.3.3 are affected, anything from 2.3.4 onward is not.

Remediation

Update to version 2.3.4, 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: JobSearch WP Job Board 2.3.4 closes this, and updating the plugin is the step that ends it.
