DESCRIPTION:
A vulnerability has been discovered in the Nmedia Users File Uploader
plugin for WordPress, which can be exploited by malicious people to
compromise a vulnerable system.
The vulnerability is caused due to the
wp-content/plugins/nmedia-user-file-uploader/doupload.php script
(when "folder" is set to a valid user name) allowing the upload of
files with arbitrary extensions to a folder inside the webroot. This
can be exploited to execute arbitrary PHP code by uploading a
malicious PHP script.
The vulnerability is confirmed in version 1.8. Prior versions may
also be affected.
SOLUTION:
Upgrade to version 2.0.
PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
