2102 prior to 21.2.0.14, or 2105 prior to 21.5.0.2. It is, therefore, affected by Denial of Service (DoS)
vulnerability. A malicious actor with access to /API/system/admins/session could cause an API denial of 
service due to improper rate limiting.

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