CVE-2024-5637
At a glance
CVE-2024-5637 is a high-severity Missing Authorization vulnerability in the Market Exporter WordPress plugin, affecting versions <= 2.0.19. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high availability impact). Exploitation requires no authentication. The issue is fixed in version 2.0.20; sites on affected versions should update now. Disclosed June 2024, reported by Lucio Sá.
Vulnerability Overview
The Market Exporter plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'remove_files' function in all versions up to, and including, 2.0.19. This makes it possible for authenticated attackers, with Subscriber-level access and above, to use path traversal to delete arbitrary files on the 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, and no interaction from a victim user. A successful exploit has high impact on availability.
CWE-862: Missing Authorization
Market Exporter <= 2.0.19 carries this weakness at remove_files, and reaching it takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Market Exporter the fix is 2.0.20: builds <= 2.0.19 are affected, anything from 2.0.20 onward is not.
Remediation
Update to version 2.0.20, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Market Exporter 2.0.20 closes this, and updating the plugin is the step that ends it.
