TITLE:
Phpauction GPL Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA15967

VERIFY ADVISORY:
http://secunia.com/advisories/15967/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, Exposure of sensitive
information

WHERE:
>From remote

SOFTWARE:
Phpauction GPL 2.x
http://secunia.com/product/5373/

DESCRIPTION:
Diabolic Crab has reported some vulnerabilities in Phpauction GPL,
which can be exploited by malicious people to disclose sensitive
information and conduct cross-site scripting and SQL injection
attacks.

1) Input passed to the "category" parameter in "adsearch.php" is not
properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "lan" parameter in "index.php" and the
"auction_id" parameter in "profile.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 a vulnerable site.

3) Input passed to the "lan" parameter in "index.php" is not properly
verified, before it is used to include files. This can be exploited to
include arbitrary files from local resources.

Successful exploitation requires that "magic_quotes_gpc" is disabled.

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

PROVIDED AND/OR DISCOVERED BY:
Diabolic Crab
