CVE-2008-0608
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Logging Server (ftplogsrv.exe) in IPSwitch WS_FTP 6.1 versions 7.9.14.0 and earlier is vulnerable to a denial of service attack via a large number of large UDP packets sent to port 5151. This causes the listening socket to terminate and prevents log commands from being recorded.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify WS_FTP installation versionCheck the installed WS_FTP version through Add/Remove Programs, the application itself, or the ftplogsrv.exe file properties. Compare against version 6.1 and verify if it is 7.9.14.0 or earlier.Affected if WS_FTP version is 6.1 at 7.9.14.0 or earlier
-
Locate the Logging Server executableSearch for ftplogsrv.exe on the system. Common locations include the WS_FTP installation directory, often under Program Files.Affected if ftplogsrv.exe is present on the system
-
Determine if the Logging Server is runningOpen Task Manager or use command 'tasklist /FI "IMAGENAME eq ftplogsrv.exe"' to check if ftplogsrv.exe is currently running as a process.Affected if ftplogsrv.exe process is running
-
Verify UDP port 5151 is listeningUse command 'netstat -an | findstr :5151' or a port scanning tool to check if UDP port 5151 is in a listening state.Affected if UDP port 5151 is open and listening
A system is affected if it runs WS_FTP 6.1 version 7.9.14.0 or earlier with the Logging Server (ftplogsrv.exe) actively running and listening on UDP port 5151.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade WS_FTP to a version newer than 7.9.14.0, or implement network-level rate limiting/filtering on UDP port 5151 to block malicious traffic patterns.
