{“lastseen”:””,”description”:”Nagios Host monitoringwizard Command Injection Remote Code Execution Vulnerability. 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 monitoringwizard module. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the service account.
