CVE-2016-8495
An improper certificate validation vulnerability in Fortinet FortiManager 5.0.6 through 5.2.7 and 5.4.0 through 5.4.1 allows remote attacker to spoof a trusted entity by using a man-in-the-middle (MITM) attack via the Fortisandbox devices probing feature.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.90%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
