TITLE:
Looking Glass Cross-Site Scripting and Shell Command Injection

SECUNIA ADVISORY ID:
SA16607

VERIFY ADVISORY:
http://secunia.com/advisories/16607/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, System access

WHERE:
>From remote

SOFTWARE:
Looking Glass
http://secunia.com/product/5627/

DESCRIPTION:
rgod has discovered some vulnerabilities in Looking Glass, which can
be exploited by malicious people to conduct cross-site scripting
attacks and compromise a vulnerable system.

1) Input passed to the "version" array parameter in footer.php and
header.php is not properly sanitised before being returned to users.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

2) Input passed to the "target" parameter in lg.php is not properly
sanitised before being used in a "system()" call. This can be
exploited to inject arbitrary shell commands via e.g. the "|" pipe
character.

NOTE: Whitespace characters are filtered making exploitation harder.

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:
rgod
