At a glance

CVE-2024-9660 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the School Management System for Wordpress WordPress plugin, affecting versions <= 91.5.0. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Student level or above. The issue is fixed in version 92.0.0; sites on affected versions should update now. Disclosed November 2024, reported by Tonn.

Vulnerability Overview

The School Management System for Wordpress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the mj_smgt_load_documets_new() and mj_smgt_load_documets() functions in all versions up to, and including, 91.5.0. This makes it possible for authenticated attackers, with Student-level access and above, 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 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

School Management System for Wordpress <= 91.5.0 carries this weakness at mj_smgt_load_documets_new(), and reaching it takes an account at Student level or above. 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 School Management System for Wordpress the fix is 92.0.0: builds <= 91.5.0 are affected, anything from 92.0.0 onward is not.

Remediation

Update to version 92.0.0, or a newer patched version

How does WordSec protect against this?

An attacker needs Student access first, so the firewall sees the attempt as traffic from a logged-in account: 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: School Management System for Wordpress 92.0.0 closes this, and updating the plugin is the step that ends it.
