"The remote host is running a version of Unraid prior to 7.3.0. It is, therefore, affected by multiple
vulnerabilities:

  - A command injection vulnerability exists in the FileUpload.php file due to the lack of proper validation
    of a user-supplied string before using it to execute a system call. An authenticated, remote attacker can
    exploit this to execute arbitrary code in the context of the www-data user. (CVE-2026-9772)

  - A command injection vulnerability exists in the ToggleState.php file due to the lack of proper validation
    of a user-supplied string before using it to execute a system call. An authenticated, remote attacker can
    exploit this to execute arbitrary code in the context of the www-data user. (CVE-2026-9773)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported
version number.");
