Hello, as you all know, it's possible to exploit a number of IIS bugs to gain access to \winnt\system32\cmd.exe and execute arbitrary commands on the server. I've been trying to convince it to execute several commands on one line (as one would separate commands with a ';' under any decent shell), with limited success : on a number of NT/2k boxes, the syntax : command1 & command2 (eg, cd .. & dir) works fine. On some other boxes, though, it only returns 'The parameter is incorrect'. It is unclear to me whether this problem happens only because of the way the request is made (http://path/to/cmd.exe?/c+command1&command2), or if there are really different versions of cmd.exe.
A suggestion: have you tried copying cmd.exe to some other filename (e.g. foo.exe) and then use *that* to execute the multiple command line? Just thinking that if redirection doesn't work without using a copy of cmd.exe, maybe some other aspects don't either.
