More information:

Maksymilian Arciemowicz of securityreason.com reported that ProFTPD is vulnerable to cross-site request forgery (CSRF) attacks and executes arbitrary FTP commands via a long ftp:// URI that leverages an existing session from the FTP client implementation in a web browser.

For the stable distribution (etch) this problem has been fixed in version 1.3.0-19etch2 and in version 1.3.1-15~bpo40+1 for backports.

For the testing (lenny) and unstable (sid) distributions this problem has been fixed in version 1.3.1-15.
