Vulnerability Overview

The Short URL plugin for WordPress is vulnerable to stored Cross-Site Scripting via the 'url_externe' parameter due to insufficient input sanitization and output escaping in versions up to, and including, 1.6.4. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 1.6.5, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
