Medium (6.3). EPSS 1.0% chance of exploitation in the next 30 days.

Bitrix24 through 25.100.300 allows Remote Code Execution because an actor with SOURCE/WRITE permissions for the Translate Module can upload and execute code by sending a PHP file and a .htaccess file. NOTE: this is disputed by the Supplier because this is intended behavior for the high-privileged users who can upload new translated pages to the website.
