21
FAUCET Score

CVE-2001-0456 describes a vulnerability in the Proftpd postinst installation script for Debian 2.2, where enabling anonymous access fails to properly downgrade the "run as uid/gid" configuration, leading to the server operating with elevated privileges. This vulnerability carries a high CVSS score of 7.5, indicating a critical risk due to its network-based attack vector, low attack complexity, and potential for partial compromise of confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this nearly two-decade-old flaw.
