Vulnerability Overview

The NextGen Gallery plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 3.1.5. This is due to the plugin unserializing serialized data obtained via user supplied input from the `sortorder` parameter. This makes it possible for authenticated attackers to call arbitrary PHP Objects and achieve remote code execution when the right gadgets are available.

Technical Analysis

REMEDIATION: Update to version 3.1.6, or a newer patched version --- IDENTIFIER: CWE-502 (Deserialization of Untrusted Data) The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
