CVE-2024-58299
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 · uneditedPCMan FTP Server 2.0 contains a buffer overflow vulnerability in the 'pwd' command that allows remote attackers to execute arbitrary code. Attackers can send a specially crafted payload during the FTP login process to overwrite memory and potentially gain system access.
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 · moderate confidencePCMan FTP Server 2.0 contains a buffer overflow vulnerability in the 'pwd' command that allows remote attackers to execute arbitrary code via a specially crafted payload sent during the FTP login process, enabling memory corruption and potential system compromise.

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.
-
Confirm PCMan FTP Server is installedCheck for PCMan FTP Server in installed programs (Windows Control Panel > Programs and Features) or look for the executable (pcman.exe or similar) in common installation directories like C:\Program Files\PCMan FTP Server or C:\Program Files (x86)\PCMan FTP ServerAffected if PCMan FTP Server is found on the system
-
Identify the installed versionRight-click the PCMan FTP Server executable, select Properties, and check the File Version in the Details tab. Alternatively, run 'pcman.exe --version' or check the About/Help menu within the application if availableAffected if Version is 2.0 or any version that matches the vulnerable release
-
Verify the FTP service is runningOpen Windows Services (services.msc) and look for 'PCMan FTP Server' service, or use command 'netstat -an | findstr :21' to check if port 21 (FTP default) is listeningAffected if The PCMan FTP Server service is running and listening on FTP port
-
Check network accessibilityFrom a remote system or using nmap locally, scan the target to verify port 21 is open and accessible (e.g., nmap -p 21 <target_ip> or telnet <target_ip> 21)Affected if Port 21 is open and accessible from the network (indicates the vulnerability is remotely exploitable)
-
Review for indicators of exploitation attemptsCheck FTP server logs (typically found in the PCMan FTP Server installation directory under Logs or similar folder) for unusual login attempts, especially those containing unusually long strings in the username field or around the 'pwd' command during login sequenceAffected if Log entries show abnormal patterns consistent with buffer overflow attempts or successful exploitation
The environment is affected if PCMan FTP Server version 2.0 is installed, the FTP service is running, and port 21 is accessible, as this combination allows remote attackers to exploit the buffer overflow in the pwd command during FTP login.

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 dataSince PCMan FTP Server 2.0 is a legacy application with likely no vendor support, remediation options include: deploying a maintained FTP server alternative, implementing network segmentation/firewall rules to restrict access to the FTP service, or disabling the service entirely if not required.
