CVE-2021-27792
The request handling functions in web management interface of Brocade Fabric OS versions before v9.0.1a, v8.2.3a, and v7.4.2h do not properly handle malformed user input, resulting in a service crash.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
