CVE-2000-0640

31
FAUCET Score

CVE-2000-0640 describes a file existence disclosure vulnerability in Guild FTPd, specifically affecting versions by Steve Poulsen. Remote attackers can leverage a directory traversal technique (using "..") to determine if files exist outside the FTP root directory by observing differing error messages. This vulnerability is rated as high severity (CVSS 7.5), indicating it can be exploited remotely with low complexity and potentially lead to partial confidentiality, integrity, and availability impacts. While there is no evidence of active exploitation or Metasploit/Nuclei modules, an ExploitDB entry confirms the availability of exploit code, though community discussion and media coverage are minimal.
