At a glance
This record tracks a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Anti-Malware Security and Brute-Force Firewall WordPress plugin, affecting versions < 4.15.23. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 4.15.23; sites on affected versions should update now. Disclosed May 2015, reported by James Hooker.
Vulnerability Overview
The Anti-Malware Security and Brute-Force Firewall plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 4.15.22 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers, if they trick an administrator to visiting a form, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Anti-Malware Security and Brute-Force Firewall < 4.15.23 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Anti-Malware Security and Brute-Force Firewall the fix is 4.15.23: builds < 4.15.23 are affected, anything from 4.15.23 onward is not.
Remediation
Update to version 4.15.23, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Anti-Malware Security and Brute-Force Firewall: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Anti-Malware Security and Brute-Force Firewall 4.15.23 closes this, and updating the plugin is the step that ends it.
