vulnerabilities:

  - Stored Cross-Site Scripting on all sensor titles, related to incorrect error handling for a %00 in the SRC
attribute of an IMG element (CVE-2017-15008)

  - Reflected Cross-Site Scripting on error.htm (the error page), via the errormsg parameter (CVE-2017-15009)

  - Stored Cross-Site Scripting on all group names created, related to incorrect error handling for an HTML
encoded script (CVE-2017-15360)

  - Arbitrary remote code execution by remote authenticated administrators by uploading a .exe file and then
proceeding in spite of the error message (CVE-2017-15651)

  - it's possible to create a Map as a read-only user, by forging a request and sending it to the server
(CVE-2017-15917)");
