Vulnerability Overview

The The Special Text Boxes plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 6.2.4. This is due to the plugin adding the filter add_filter('comment_text', 'do_shortcode'); which will run all shortcodes in comments. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

Technical Analysis

REMEDIATION: Update to version 6.2.5, or a newer patched version --- IDENTIFIER: CWE-94 (Improper Control of Generation of Code ('Code Injection')) The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
