"The version of NUUO NVRMini2 installed on the remote host is affected
by multiple vulnerabilities:

  - NUUO NVRMini2 web server utilizes CGI binaries in order to handle
    a variety of commands that require authenticated interaction.
    Implemented session handling mechanism doesn't validate user's
    input properly. Malicious attackers can trigger stack overflow
    in session management routines in order to execute arbitrary
    code. (CVE-2018-1149)

  - NUUO NVRMini2 web server contains back door functionality. Back
    door PHP code (when enabled) allows unauthenticated attacker to
    change a password for any registered user except administrator
    of the system. (CVE-2018-1150)");
