Serv-U FTP server is a secure, advanced FTP server for Windows. However, like most programs, it is not completely bugfree. I (and maybe more people with me) found this bug some time ago. It can be triggered as *every* user that can log in, anonymous included, and exists in possibly every version. (At least 4.x and 5.x series). The exploit might be a cliché but it might threaten (hosting and other) companies that use this FTP server. Following commands will trigger the crash: STOU COM1 STOU LPT1 STOU PRN STOU AUX However, "STOU NUL" does NOT work. Greetings, Patrick
