At a glance

CVE-2022-45377 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Drag and Drop Multiple File Upload for WooCommerce WordPress plugin, affecting versions <= 1.0.8. 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 1.0.9; sites on affected versions should update now. Disclosed February 2023, reported by István Márton.

Vulnerability Overview

The Drag and Drop Multiple File Upload for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.8. This is due to missing or incorrect nonce validation on the upload and delete_file functions. This makes it possible for unauthenticated attackers to perform an unauthorized file upload or deletion via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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 Drag and Drop Multiple File Upload for WooCommerce <= 1.0.8 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 Drag and Drop Multiple File Upload for WooCommerce the fix is 1.0.9: builds <= 1.0.8 are affected, anything from 1.0.9 onward is not.

Remediation

Update to version 1.0.9, or a newer patched version

How does WordSec protect against this?
