"According to its self-reported version, the instance of FatPipe MPVPN running on the remote web server is <
10.1.2r60p91 or 10.2.2 < 10.2.2r42. It is, therefore, affected by multiple vulnerabilities, including:

    - FatPipe WARP, IPVPN, and MPVPN software prior to versions 10.1.2r60p91 and 10.2.2r42 includes an account named
      'cmuser' that has administrative privileges and no password. (CVE-2021-27856)

    - FatPipe WARP, IPVPN, and MPVPN software prior to versions 10.1.2r60p91 and 10.2.2r42 allows a remote,
      authenticated attacker with read-only privileges to grant themselves administrative privileges. (CVE-2021-27855)

    - A missing authorization vulnerability in the web management interface of FatPipe WARP, IPVPN, and MPVPN software
      prior to versions 10.1.2r60p91 and 10.2.2r42 allows an authenticated, remote attacker with read-only privileges to
      create an account with administrative privileges. (CVE-2021-27859)

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