Authenticated code execution via crafted plugin archive

Published Apr 28, 2023 · Updated Jan 30, 2025

Arbitrary file upload in Textpattern 4.8.8 allows remote authenticated users to execute code by uploading a crafted plugin archive. The plugin installer accepts a ZIP containing a PHP file and exposes the extracted file beneath the web-accessible plugins path, where a direct request executes it. A valid account with plugin-upload access is required, and resulting commands run with the web server process's permissions.
