"The version of Adobe Connect running on the remote host is 11.2.1 or earlier. It is, therefore, affected by privilege
escalation vulnerability. The vulnerability exists due to improper access restrictions. A remote attacker can bypass
implemented security restrictions and gain unauthorized access to the application.

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