Vulnerability Overview
The all-in-one-files-upload-for-woocommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in versions 2.0.3 to 2.0.16 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG 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, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in All in One Files Upload for WooCommerce 2.0.3 – 2.0.16 takes no account at all. 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 All in One Files Upload for WooCommerce the fix is 2.0.17: builds 2.0.3 – 2.0.16 are affected, anything from 2.0.17 onward is not.
Remediation
Update to version 2.0.17, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: All in One Files Upload for WooCommerce 2.0.17 closes this, and updating the plugin is the step that ends it.
