CVE-1999-0997

33
FAUCET Score

CVE-1999-0997 describes a critical vulnerability in wu-ftp, specifically when FTP conversion is enabled, allowing attackers to execute arbitrary commands. This flaw affects various distributions of wu-ftpd, including those from Millenux GmbH, Red Hat, and the University of Washington. With a CVSS score of 7.5 (HIGH), it presents a significant risk due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability. While not listed on the KEV catalog or Hot List, and with no active Metasploit or Nuclei exploits, an ExploitDB entry (EDB-20563) confirms the existence of exploit code, though community discussion and media coverage are minimal.
