22.3R3, 22.5 prior to 22.5R2, 22.6 prior to 22.6R2, or 22.7 prior to 22.7R2. It is, therefore, affected by an
authentication bypass vulnerability:

  - Incorrect implementation of an authentication algorithm in Ivanti vTM other than versions 22.2R1 or 22.7R2 allows a
    remote unauthenticated attacker to bypass authentication of the admin panel. (CVE-2024-7593)

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