CVE-2021-36171
The use of a cryptographically weak pseudo-random number generator in the password reset feature of FortiPortal before 6.0.6 may allow a remote unauthenticated attacker to predict parts of or the whole newly generated password within a given time frame.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
