CVE-2017-14705 is a high-severity flaw (CVSS 8.1) affecting i-suite, web application firewall. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

DenyAll WAF before 6.4.1 allows unauthenticated remote command execution via TCP port 3001 because shell metacharacters can be inserted into the type parameter to the tailDateFile function in /webservices/stream/tail.php. An iToken authentication parameter is required but can be obtained by exploiting CVE-2017-14706. This affects DenyAll i-Suite LTS 5.5.0 through 5.5.12, i-Suite 5.6, Web Application Firewall 5.7, and Web Application Firewall 6.x
