At a glance

CVE-2015-0895 is a low-severity Cross-Site Request Forgery (CSRF) vulnerability in the All-In-One Security (AIOS) WordPress plugin, affecting versions <= 3.8.9. It carries a CVSS score of 3.1 (reachable over the network). Exploitation requires no authentication. The issue is fixed in version 3.9.0; sites on affected versions should update now. Disclosed March 2015.

Vulnerability Overview

Cross-site request forgery (CSRF) vulnerability in the All In One WP Security & Firewall plugin before 3.9.0 for WordPress allows remote attackers to hijack the authentication of administrators for requests that delete logs of 404 (aka Not Found) HTTP status codes.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site.

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

Reaching this weakness in All-In-One Security (AIOS) <= 3.8.9 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 All-In-One Security (AIOS) the fix is 3.9.0: builds <= 3.8.9 are affected, anything from 3.9.0 onward is not.

Remediation

Update to version 3.9.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to All-In-One Security (AIOS): WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: All-In-One Security (AIOS) 3.9.0 closes this, and updating the plugin is the step that ends it.
