Vulnerability
The open-source FTP server program ProFTPd was exposed to an unauthorized file copying vulnerability, which is caused by the mod_copy module in ProFTPd. The mod_copy module of ProFTPd was originally used for file copy operations, but in the vulnerable version, the relevant command operations of the mod_copy module did not set access authorization verification, resulting in any client being able to copy any file in the system through a specific command.
Impact:
Attackers can use this vulnerability to obtain system-sensitive files, obtain server permissions, and so on.
Mitigation / Precaution
In order to patch this vulnerability, we suggest you update ProFTPd to the latest version.
