Vulnerability Overview

An issue was discovered in the svg-vector-icon-plugin (aka WP SVG Icons) plugin through 3.2.2 for WordPress. wp-admin/admin.php?page=wp-svg-icons-custom-set mishandles Custom Icon uploads. CSRF leads to upload of a ZIP archive containing a .php file.

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)

Reaching this weakness in WP SVG Icons < 3.2.3 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 WP SVG Icons the fix is 3.2.3: builds < 3.2.3 are affected, anything from 3.2.3 onward is not.

Remediation

Update to version 3.2.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP SVG Icons: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP SVG Icons 3.2.3 closes this, and updating the plugin is the step that ends it.
