Remote Code Execution in PHP Ping

php-ping is a simple php script executing the 'ping' command. A bug in this script allows users to execute arbitrary commands. The problem is based upon the fact that not all user inputs are filtered correctly: although $host is filtered using preg_replace(), the $count variable is passed unfiltered to the system() command.

No known solution was made available for at least one year since the disclosure of this vulnerability. Likely none will be provided anymore. General solution options are to upgrade to a newer release, disable respective features, remove the product or replace the product by another one.
