Vulnerability Overview

The Transposh WordPress Translation plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.9.1. This is due to missing nonce validation on several AJAX action function. This makes it possible for unauthenticated attackers to performa variety of actions such as initiating a back-up, changing the plugin's settings, and deleting duplicates via forged requests granted they can trick a site administrator into performing an action such as clicking on a link.

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.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Transposh WordPress Translation <= 1.0.9.1 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Transposh WordPress Translation the fix is 1.0.9.2: builds <= 1.0.9.1 are affected, anything from 1.0.9.2 onward is not.

Remediation

Update to version 1.0.9.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Transposh WordPress Translation: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Transposh WordPress Translation 1.0.9.2 closes this, and updating the plugin is the step that ends it.
