At a glance

CVE-2024-8615 is a critical-severity Unrestricted Upload of File with Dangerous Type vulnerability in the JobSearch WP Job Board WordPress plugin, affecting versions <= 2.6.7. It carries a CVSS score of 10.0 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.6.8; sites on affected versions should update now. Disclosed November 2024, reported by Tonn.

Vulnerability Overview

The JobSearch WP Job Board plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the jobsearch_location_load_excel_file_callback() function in all versions up to, and including, 2.6.7. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

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 confidentiality, integrity, availability — full site compromise territory.

CWE-434: Unrestricted Upload of File with Dangerous Type

JobSearch WP Job Board <= 2.6.7 carries this weakness at jobsearch_location_load_excel_file_callback(), and reaching it takes no account at all. An unrestricted file upload lets a caller store a file whose type or destination the application does not properly constrain.

If an uploaded file lands anywhere the server will execute, the flaw becomes remote code execution and the site should be treated as fully compromised. For JobSearch WP Job Board the fix is 2.6.8: builds <= 2.6.7 are affected, anything from 2.6.8 onward is not.

Remediation

Update to version 2.6.8, 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. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: JobSearch WP Job Board 2.6.8 closes this, and updating the plugin is the step that ends it.
