Technical details
A vulnerability exists in certain implementations of the FTP daemon (ftpd) related to the handling of the 'Change Working Directory' (CWD) command. When a user provides the '~root' argument to the CWD command, the daemon incorrectly resolves the path, granting the user access to the root user's home directory or elevated privileges. This is a remote, unauthenticated attack vector that results in a complete compromise of confidentiality, integrity, and availability. The flaw stems from improper validation of tilde-expansion in the FTP service.
