DESCRIPTION:
FOX_MULDER has discovered a vulnerability in PHP Net Tools, which
potentially can be exploited by malicious people to compromise a
vulnerable system.

Input passed to the "host" parameter in "nettools.php" isn't properly
sanitised before being used when executing a shell command. This can
be exploited to inject and execute arbitrary shell commands via the
"|" pipe character.

NOTE: The vendor recommends in the documentation to restrict access
to the "nettools.php" script to prevent misuse.

The vulnerability has been confirmed in version 2.7.1. Other versions
may also be affected.

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