At a glance
CVE-2022-2441 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the ImageMagick Engine WordPress plugin, affecting versions <= 1.7.5. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.7.6; sites on affected versions should update now. Disclosed October 2022, reported by Rasoul Jahanshahi.
Vulnerability Overview
The ImageMagick Engine plugin for WordPress is vulnerable to remote code execution via the 'cli_path' parameter in versions up to, and including 1.7.5. This makes it possible for unauthenticated users to run arbitrary commands leading to remote command execution, granted they can trick a site administrator into performing an action such as clicking on a link. This makes it possible for an attacker to create and or modify files hosted on the server which can easily grant attackers backdoor access to the affected server.
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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-352: Cross-Site Request Forgery (CSRF)
ImageMagick Engine <= 1.7.5 carries this weakness at cli_path, and reaching it 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 ImageMagick Engine the fix is 1.7.6: builds <= 1.7.5 are affected, anything from 1.7.6 onward is not.
Remediation
Update to version 1.7.6, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to ImageMagick Engine: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: ImageMagick Engine 1.7.6 closes this, and updating the plugin is the step that ends it.
