TITLE:
Zorum prod.php Arbitrary Command Execution Vulnerability

SECUNIA ADVISORY ID:
SA16504

VERIFY ADVISORY:
http://secunia.com/advisories/16504/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Zorum 2.x
http://secunia.com/product/472/
Zorum 3.x
http://secunia.com/product/1000/

DESCRIPTION:
rgod has discovered a vulnerability in Zorum, which can be exploited
by malicious people to compromise a vulnerable system.

Input passed to the "argv[1]" parameter in gorum/prod.php is not
properly sanitised before being used in the "system()" function. This
can be exploited to execute arbitrary commands on the server.

Example:
http://[host]/zorum/gorum/prod.php?argv[1]=|[command]

Successful exploitation requires that "register_globals" is enabled
and "register_argc_argv" is disabled.

The vulnerability has been confirmed in version 3.5. Other versions
may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
