DESCRIPTION:
Dang Hai Son has discovered a vulnerability in OpenCart, which can be
exploited by malicious people to manipulate certain data.

Input passed to "country_id" in index.php (when "route" is set to
"account/register/zone") is not properly sanitised in
system/library/cache.php before being used to create cache files.
This can be exploited to overwrite arbitrary files via directory
traversal attacks and URL-encoded NULL bytes.

The vulnerability is confirmed in version 1.5.1.1. Prior versions may
also be affected.

SOLUTION:
Update to version 1.5.1.2.
