Dc Woocommerce Multi Vendor - Privilege Escalation (CVE-2024-8289)

Q: Am I affected by this vulnerability?

You are affected if your site runs Dc Woocommerce Multi Vendor. Versions below 4.2.1 are vulnerable; that release and later are not. No account is needed to exploit this, so a public site is reachable by anyone.

Q: How do I fix it?

Update Dc Woocommerce Multi Vendor to version 4.2.1 or later. That is the complete fix. Until you can update, Unauthorised administrator detection in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Privilege Escalation flaw. An attacker who exploits it can raise a low-privilege account, or none at all, to administrator.

CVE-2024-8289

Vulnerability CVE-2024-8289 PLUGIN dc-woocommerce-multi-vendor CRITICAL

The MultiVendorX – The Ultimate WooCommerce Multivendor Marketplace Solution plugin for WordPress is vulnerable to privilege escalation/de-escalation and account takeover due to an insufficient capability check on the update_item_permissions_check and create_item_permissions_check functions in all versions up to, and including, 4.2.0. This makes it possible for unauthenticated attackers to change the password of any user with the vendor role, create new users with the vendor role, and demote other users like administrators to the vendor role.
