TITLE:
zKup PHP Code Execution and Security Bypass

SECUNIA ADVISORY ID:
SA29276

VERIFY ADVISORY:
http://secunia.com/advisories/29276/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
zKup 2.x
http://secunia.com/product/17920/

DESCRIPTION:
Charles "real" F. has discovered two vulnerabilities in zKup, which
can be exploited by malicious people to manipulate data and
compromise a vulnerable system.

1) The admin/configuration/modifier.php script does not properly
restrict access to legitimate users. This can be exploited to create
new administrators.

2) Input passed to the "login" parameter in
admin/configuration/modifier.php is not properly sanitised before
being stored. This can be exploited to inject and execute arbitrary
PHP code via a specially crafted parameter value containing a NULL
byte.

Successful exploitation of this vulnerability requires that
"magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 2.03. Other versions may
also be affected.

SOLUTION:
Restrict access to the "admin/configuration/modifier.php" script
(e.g. with ".htaccess").

PROVIDED AND/OR DISCOVERED BY:
Charles "real" F.
