Technical details
A remote code execution (RCE) vulnerability exists within the PluXml CMS theme editor due to improper control of file generation (CWE-94). The flaw is located in the 'minify.php' file within the default theme directory (/themes/defaut/css/minify.php). An attacker with administrative privileges can use the built-in theme editor to overwrite this file with arbitrary PHP code. Because the application does not sufficiently restrict the content or execution of this file, the injected code can be used to execute system-level commands on the host server. This vulnerability requires network access and high-level (Administrator) authentication.
