CRITICAL:

WHERE:
From remote

SOFTWARE:
Network Query Tool 1.x

DESCRIPTION:
Janek Vind has reported a vulnerability in Network Query Tool,
allowing malicious people to conduct Cross Site Scripting attacks.

1) If error messages hasn't been turned off in PHP, the "nqt.php"
script will return error messages if an invalid value is supplied to
the "portNum" parameter. This can be exploited to reveal the
installation path.

2) Input passed to the "portNum" parameter in the "nqt.php" script
isn't properly verified before it is returned to the user. This can
be exploited to execute arbitrary HTML or script code in a user's
browser session in context of an affected site by tricking the user
into visiting a malicious website or follow a specially crafted
link.

The vulnerabilities have been reported in version 1.6. Prior versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
