Description
Rapid7 InsightVM versions before 8.34.0 contain a signature verification issue on the Assertion Consumer Service (ACS) cloud endpoint that could allow an attacker to gain unauthorized access to InsightVM accounts setup via "Security Console" installations, resulting in full account takeover. The issue occurs due to the application processing these unsigned assertions and issuing session cookies that granted access to the targeted user accounts. This has been fixed in version 8.34.0 of InsightVM.
