ProFTPD through 1.3.9e and 1.3.10rc1 through 1.3.10rc4 contains a link-following vulnerability in mod_copy that allows authenticated FTP users to bypass Limit WRITE restrictions via symlinks. Attackers can place a symlink in a writable directory and use SITE COPY or SITE CPTO to overwrite files in write-denied locations.
