13.0 before 13.0-92.21, 13.1 before 13.1-51.15, or 14.1 before 14.1-12.35. It is, therefore, affected by multiple
vulnerabilities: 

  - Authenticated (low privileged) remote code execution on Management Interface (CVE-2023-6548)

  - Denial of Service (CVE-2023-6549)

Please refer to advisory CTX584986 for more information.

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