At a glance

CVE-2023-48275 is a medium-severity Unrestricted Upload of File with Dangerous Type vulnerability in the Widgets for Google Reviews WordPress plugin, affecting versions <= 11.0.2. It carries a CVSS score of 6.6 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Editor level or above. The issue is fixed in version 11.1; sites on affected versions should update now. Disclosed November 2023, reported by Rafie Muhammad.

Vulnerability Overview

Multiple plugins for WordPress by Trustindex.io are vulnerable to arbitrary file uploads due to missing file type validation in the ~/tabs/feature_request.php file in various versions. This makes it possible for authenticated attackers, with editor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. This vulnerability may only be fully exploitable for RCE in unique scenarios where the server is overloaded and the unlink() is not triggered immediately following move_uploaded_file().

Technical Analysis

The vector marks this flaw as remotely reachable over the network, 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

Widgets for Google Reviews <= 11.0.2 carries this weakness at unlink(), and reaching it takes an account at Editor 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 Widgets for Google Reviews the fix is 11.1: builds <= 11.0.2 are affected, anything from 11.1 onward is not.

Remediation

Update to version 11.1, or a newer patched version

How does WordSec protect against this?

An attacker needs Editor 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: Widgets for Google Reviews 11.1 closes this, and updating the plugin is the step that ends it.
