TITLE:
Ultimate Auction Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA18477

VERIFY ADVISORY:
http://secunia.com/advisories/18477/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
From remote

SOFTWARE:
Ultimate Auction 3.x
http://secunia.com/product/6826/

DESCRIPTION:
Querkopf has reported two vulnerabilities in Ultimate Auction, which
can be exploited by malicious people to conduct cross-site scripting
attacks.

Input passed to the "item" parameter in "item.pl" and the "category"
parameter in "itemlist.pl" isn't properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

Examples:
http://[victim]/cgi-local/auktion/item.pl/item.pl?item=[code]
http://[victim]/cgi-local/auktion/itemlist.pl?category=[code]

The vulnerabilities have been reported in version 3.67 and prior.
Other versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
Querkopf
