Title: Network Query Tool Remote Command Execution Vulnerability
Severity: HIGH
Description:
Network Query Tool is a PHP tool allowing the user to collect a variety of information about a given domain or IP address, such as DNS lookup and traceroute. An input validation error in the script allows a remote user to pass an arbitrary shell command which will be executed by the script.
The script nqt.php accepts a parameter called 'target'. The value of this variable is passed directly to the shell. It is possible to embed shell commands in this variable that will be executed when the command is executed.
It may be possible for remote attackers to gain interactive access to the host by exploiting this vulnerability. It is significantly easier to gain superuser privileges if interactive (or 'local') access can be obtained.
