Vulnerability Overview

PHP remote file inclusion vulnerability in the Gwolle Guestbook plugin before 1.5.4 for WordPress, when allow_url_include is enabled, allows remote authenticated users to execute arbitrary PHP code via a URL in the abspath parameter to frontend/captcha/ajaxresponse.php. NOTE: this can also be leveraged to include and execute arbitrary local files via directory traversal sequences regardless of whether allow_url_include is enabled.

Technical Analysis

REMEDIATION: Update to version 1.5.4, or a newer patched version --- IDENTIFIER: CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')) The PHP application receives input from an upstream component, but it does not restrict or incorrectly restricts the input before its usage in require, include, or similar functions.
