TITLE:
OpenCart Script Insertion and Cross-Site Scripting

SECUNIA ADVISORY ID:
SA30177

VERIFY ADVISORY:
http://secunia.com/advisories/30177/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
OpenCart 0.x
http://secunia.com/product/19206/

DESCRIPTION:
Thomas Pollet has discovered two vulnerabilities in OpenCart, which
can be exploited by malicious people to conduct cross-site scripting
and script insertion attacks.

1) Input passed to the "firstname" parameter in index.php (when
"controller" is set to "account_create") is not properly sanitised
before being stored. This can be exploited to insert arbitrary HTML
and script code, which is executed in a user's browser session in
context of an affected site when the malicious data is viewed.

2) Input passed to the "search" parameter in index.php (when
"controller" is set to "search" and "action" to "page") is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

The vulnerabilities are confirmed in version 0.7.7. Other versions
may also be affected.

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