on the remote host is 12.x prior to 12.1.7454.7000 or 14.x prior
to 14.2.5323.2000. It is, therefore, affected by multiple vulnerabilities.
- An authentication bypass vulnerability exists in the second layer
of password protection. An authenticated, local attacker can
exploit this to bypass authentication and execute arbitrary
actions with local administrator privileges. (CVE-2019-12756)
- A privilege escalation vulnerability exists. An unauthenticated,
local attacker can exploit this to gain privileged access to the
system. (CVE-2019-12757, CVE-2019-18372)
- A remote command execution vulnerability exists due to an unsigned
code execution vulnerability. An unauthenticated, remote attacker
can exploit this to execute code without a resident proper digital
signature. (CVE-2019-12758)
Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
