CVE-2002-0628
The Telnet service for Polycom ViewStation before 7.2.4 does not restrict the number of failed login attempts, which makes it easier for remote attackers to guess usernames and passwords via a brute force attack.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.19%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
