CVE-2024-9307
At a glance
CVE-2024-9307 is a critical-severity Unrestricted Upload of File with Dangerous Type vulnerability in the mFolio Lite WordPress plugin, affecting versions <= 1.2.1. It carries a CVSS score of 9.9 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 1.2.2; sites on affected versions should update now. Disclosed November 2024, reported by Francesco Carlucci.
Vulnerability Overview
The mFolio Lite plugin for WordPress is vulnerable to file uploads due to a missing capability check in all versions up to, and including, 1.2.1. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file or upload arbitrary EXE files on the affected site's server which may make remote code execution possible if the attacker can also gain access to run the .exe file, or trick a site visitor into downloading and running the .exe file.
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
Reaching this weakness in mFolio Lite <= 1.2.1 takes an account at Author 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 mFolio Lite the fix is 1.2.2: builds <= 1.2.1 are affected, anything from 1.2.2 onward is not.
Remediation
Update to version 1.2.2, or a newer patched version
How does WordSec protect against this?
An attacker needs Author 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: mFolio Lite 1.2.2 closes this, and updating the plugin is the step that ends it.
