Unrestricted file upload vulnerability in webadmin/ajaxfilemanager/ajaxfilemanager.php in Netsweeper before 3.1.10, 4.0.x before 4.0.9, and 4.1.x before 4.1.2 allows remote authenticated users with admin privileges on the Cloud Manager web console to execute arbitrary PHP code by uploading a file with a double extension, then accessing it via a direct request to the file in webadmin/deny/images/, as demonstrated by secuid0.php.gif.
