At a glance

CVE-2023-33310 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Unite Gallery Lite WordPress plugin, affecting versions <= 1.7.59. It carries a CVSS score of 5.0 (reachable over the network; high confidentiality impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 1.7.60; sites on affected versions should update now. Disclosed May 2023, reported by yuyudhn.

Vulnerability Overview

The Unite Gallery Lite plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 1.7.59 via the 'view' parameter. This allows authenticated attackers with administrator-level privileges to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

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.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Unite Gallery Lite <= 1.7.59 carries this weakness at view, and reaching it takes an account at Administrator level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Unite Gallery Lite the fix is 1.7.60: builds <= 1.7.59 are affected, anything from 1.7.60 onward is not.

Remediation

Update to version 1.7.60, or a newer patched version

How does WordSec protect against this?

An attacker needs Administrator 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. None of that substitutes for the fix: Unite Gallery Lite 1.7.60 closes this, and updating the plugin is the step that ends it.
