IMPACT:
Security Bypass, System access
WHERE:

SOFTWARE:

DESCRIPTION:
Raz0r has discovered some vulnerabilities in Shop-Script FREE, which
can be exploited by malicious people to bypass certain security
restrictions and compromise a vulnerable system.
1) The admin.php script does not properly restrict access to logged
in users and can be exploited with an HTTP client that does not
follow redirects.
2) Input passed to the "colscount", "darkcolor", and "productscount"
parameters in admin.php is not properly sanitised before it is
written to the cfg/appearence.inc.php file which is included by the
index.php script. This can be exploited to execute arbitrary PHP
code.
Successful exploitation of this vulnerability requires valid
administrator credentials (but see vulnerability #1).
The vulnerabilities are confirmed in version 2.0 and reported in
version 1.2. Other versions may also be affected.
SOLUTION:
Restrict access to the "admin.php" script (e.g. with ".htaccess").
