CVE-2007-6737: G.rodola Pyftpdlib

High severity, CVSS 7.5. EPSS: 2.1% chance of exploitation in the next 30 days.

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.

Affected products
