WordPress Contus Vblog Plugin Arbitrary File Upload Vulnerability


Description   Sammy Forgit has discovered a vulnerability in the Contus Vblog 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/contus-vblog/save.php script improperly validating uploaded files, which can be exploited to execute arbitrary PHP code by uploading a PHP file which gets an ".jpg" extension appended.
Successful exploitation requires that Apache is not configured to handle the mime-type for media files with a ".jpg" extension (Configured to handle by default).
The vulnerability is confirmed in version 1.0. Other versions may also be affected.
