http://secunia.com/advisories/17603/

CRITICAL:
Highly critical

IMPACT:
Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
AlstraSoft Template Seller Pro 3.x
http://secunia.com/product/6134/

DESCRIPTION:
Robin Verton has reported two vulnerabilities in AlstraSoft Template
Seller Pro, which can be exploited by malicious people to conduct SQL
injection attacks and compromise a vulnerable system.

1) Input passed to the "config[basepath]" parameter in
"include/paymentplugins/payment_paypal.php" isn't properly verified,
before it is used to include files. This can be exploited to include
arbitrary files from external and local resources.

Successful exploitation requires that "register_globals" is enabled.

2) Input passed to the username field when logging into the
administration interface 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.

The vulnerabilities have been reported in version 3.25. Other
versions may also be affected.

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