DESCRIPTION:
A weakness and a vulnerability have been discovered in the WP
Marketplace plugin for WordPress, which can be exploited by malicious
people to enumerate files on an affected system and compromise a
vulnerable system.

1) Input passed via the POST parameters to
wp-content/plugins/wpmarketplace/uploadify/check.php is not properly
sanitised before being used to check for the existence of files. This
can be exploited to enumerate existing files via directory traversal
sequences.

2) The wp-content/plugins/wpmarketplace/uploadify/uploadify.php
script allows upload of files with arbitrary extensions to a folder
inside the webroot. This can be exploited to e.g. execute arbitrary
PHP code by uploading a malicious PHP script.

The weakness and vulnerability are confirmed in version 1.2.1. Prior
versions may also be affected.

SOLUTION:
Update to version 1.2.2.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
