A session ID was identified in the request URL as well as a cookie value. Session IDs should not be sent in GET requests as they maybe captured by proxy systems, stored in browser history, or stored in log files. If an attacker were to get access to the session ID they would potentially be able to gain access to the target account.
As request headers are rarely logged or captured by third party systems, ensure session ID
values are only sent in cookies (assigned via
Set-Cookie response headers) and never sent
in the request URL.
