TITLE:
Alkalay nslookup Shell Command Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA16880

VERIFY ADVISORY:
http://secunia.com/advisories/16880/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Alkalay nslookup
http://secunia.com/product/5743/

DESCRIPTION:
sullo has discovered some vulnerabilities in Alkalay nslookup, which
can be exploited by malicious people to compromise a vulnerable
system.

Input passed to the "type", "query", and "ns" parameters in
"nslookup.cgi" isn't properly sanitised before being used in an
"open()" call. This can be exploited to inject and execute arbitrary
shell commands via the "|" pipe character.

The vulnerabilities have been confirmed in the latest available
version. Other versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
