Name of the Vulnerable Software and Affected Versions RSFiles versions prior to 1.17.12
Description The RSFiles Joomla extension contains a flaw allowing unauthenticated arbitrary file upload. This issue occurs via a split-controller upload bypass and a direct write task, enabling attackers to upload executable files to the /downloads/ directory, which leads to full Remote Code Execution (RCE), a state where an attacker can execute arbitrary commands on the server.
Recommendations Update to version 1.17.12.
