CVE-2017-15999
The attacker can either crack this hash or use it for further attacks where only the hash value is required.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.69%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
