"According to the self-reported version of Nagios XI, the remote host is affected by a vulnerability related to the
generation of API keys. Nagios XI before 5.11.3 2024R1 was discovered to improperly handle API keys generation
(randomly-generated), allowing attackers to possibly generate the same set of API keys for all users and utilize them to
authenticate.

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