At a glance
CVE-2014-9013 is a high-severity Improper Authentication vulnerability in the WP Marketplace WordPress plugin, affecting versions < 2.4.1. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 2.4.1; sites on affected versions should update now. Disclosed March 2015, reported by Kacper Szurek.
Vulnerability Overview
The ajaxinit function in wpmarketplace/libs/cart.php in the WP Marketplace plugin 2.4.0 for WordPress allows remote authenticated users to create arbitrary users and gain admin privileges via a request to wpmp_pp_ajax_call with an execution target of wp_insert_user.
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-287: Improper Authentication
Reaching this weakness in WP Marketplace < 2.4.1 takes a caller who can reach the endpoint. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.
An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. For WP Marketplace the fix is 2.4.1: builds < 2.4.1 are affected, anything from 2.4.1 onward is not.
Remediation
Update to version 2.4.1, 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: WP Marketplace 2.4.1 closes this, and updating the plugin is the step that ends it.
