The Logging Server (ftplogsrv.exe) 7.9.14.0 and earlier in IPSwitch WS_FTP 6.1 allows remote attackers to cause a denial of service (loss of responsiveness) via a large number of large packets to port 5151/udp, which causes the listening socket to terminate and prevents log commands from being recorded, a different vulnerability than CVE-2007-3823.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
