CVE-2007-6737
FTPServer.py in pyftpdlib before 0.2.0 does not increment the attempted_logins count for a USER command that specifies an invalid username, which makes it easier for remote attackers to obtain access via a brute-force attack.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
