Vulnerability Overview

The NextGen Gallery plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the is_image_file function in versions up to, and including, 2.0.65. This makes it possible for authenticated attackers with upload privileges to upload arbitrary files on the affected sites server which may make remote code execution possible.

Technical Analysis

REMEDIATION: Update to version 2.0.66, or a newer patched version --- IDENTIFIER: CWE-434 (Unrestricted Upload of File with Dangerous Type) The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
