This vulnerability allows remote attackers to execute arbitrary code on affected installations of Nagios Host. Authentication is required to exploit this vulnerability.\n\nThe specific flaw exists within the esensors_websensor_configwizard_func method. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call.
