Package        : proftpd-dfsg
Vulnerability  : missing input validation
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2008-4242
Debian Bug     : 502674
BugTraq ID     : 31289

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.

We recommend that you upgrade your proftpd-dfsg package.
