What is CVE-2017-16941?

October CMS versions up to 1.0.428 are susceptible to a remote code execution vulnerability caused by improper handling of .htaccess files within theme uploads. This flaw enables authenticated users to exploit the system by downloading a theme ZIP file, modifying it to include a malicious .php and .htaccess file, and then uploading the altered archive back to the platform. This could allow an attacker, who has gained access to an account with theme management permissions, to execute arbitrary PHP code on the server.
