DESCRIPTION:
A vulnerability has been discovered in the Cimy User Extra Fields
Plugin for WordPress, which can be exploited by malicious users and
malicious people to compromise a vulnerable system.

The vulnerability is caused due to the
wp-content/plugins/cimy-user-extra-fields/cimy_uef_functions.php
script allowing the upload of files with arbitrary extensions to a
folder inside the webroot when editing a user profile or registering
a new account. This can be exploited to execute arbitrary PHP code by
uploading a malicious PHP script.

Successful exploitation requires that a field of type "avatar" is
configured and a user account or the "Anyone can register" setting to
be enabled. 

The vulnerability is confirmed in version 2.3.7. Other versions may
also be affected.

SOLUTION:
No official solution is currently available.
