TITLE:
phpAdsNew Disclosure of Path Information and SQL Injection

SECUNIA ADVISORY ID:
SA17464

VERIFY ADVISORY:
http://secunia.com/advisories/17464/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of system information

WHERE:
>From remote

SOFTWARE:
phpAdsNew 2.x
http://secunia.com/product/4585/

DESCRIPTION:
Toni Koivunen has discovered a vulnerability and a weakness in
phpAdsNew, which can be exploited by malicious people to disclose
system information and conduct SQL injection attacks.

1) Input passed to the "sessionID" cookie parameter in "logout.php"
isn't properly sanitised before being used in a SQL query. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

2) The problem is that it is possible to disclose the full path to
"misc/revisions/create.php" by accessing it directly. This can
further be exploited to list installed scripts by accessing
"libraries/defaults/revisions.txt".

It is also possible to disclose the full path to other scripts by
accessing them directly. However, this require that "display_errors"
is enabled which is not a recommended setting for production
systems.

The vulnerability and the weakness have been confirmed in version
2.0.6. Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
restrict access to "misc/revisions/create.php" and
"libraries/defaults/revisions.txt".

PROVIDED AND/OR DISCOVERED BY:
Toni Koivunen
