CVE-2017-9390 is a medium-severity cross-site scripting vulnerability in n/a, published on 17 Jun 2019. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
An issue was discovered on Vera VeraEdge 1.7.19 and Veralite 1.7.481 devices. The device provides a shell script called connect.sh which is supposed to return a specific cookie for the user when the user is authenticated to https://home.getvera.com. One of the parameters retrieved by this script is "RedirectURL". However, the application lacks strict input validation of this parameter and this allows an attacker to execute the client-side code on this application.
