Technical details
The template_editor.php admin interface fails to properly validate the folder parameter, allowing directory traversal sequences (e.g., ../) to be supplied. Authenticated administrators with manage_template_access permission can exploit this to write arbitrary PHP files anywhere on the filesystem, achieving remote code execution as the web server user. A fix is available in version 5.5.3-#197 and later.
