System access
WHERE:
>From remote
SOFTWARE:
Netquery 3.x
http://secunia.com/product/5439/
DESCRIPTION:
rgod has discovered a vulnerability in Netquery, which can be
exploited by malicious people to compromise a vulnerable system.
Input passed to the "host" parameter in nquser.php is not properly
sanitised before being used as command line argument to the "dig"
command. This can be exploited to inject arbitrary shell commands
via the "|" character.
Successful exploitation requires that "magic_quotes_gpc" is
disabled.
The vulnerability has been confirmed in version 3.11. Other versions
may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
PROVIDED AND/OR DISCOVERED BY:
