Zimbra Collaboration Autodiscover Servlet XXE / ProxyServlet SSRF

Posted Apr 11, 2019

Authored by Jacob Robles, Khanh Viet Pham, An Trinh | Site metasploit.com

This Metasploit module exploits an XML external entity vulnerability and a server side request forgery to get unauthenticated code execution on Zimbra Collaboration Suite. The XML external entity vulnerability in the Autodiscover Servlet is used to read a Zimbra configuration file that contains an LDAP password for the zimbra account. The zimbra credentials are then used to get a user authentication cookie with an AuthRequest message. Using the user cookie, a server side request forgery in the Proxy Servlet is used to proxy an AuthRequest with the zimbra credentials to the admin port to retrieve an admin cookie. After gaining an admin cookie the Client Upload servlet is used to upload a JSP webshell that can be triggered from the web server to get command execution on the host. The issues reportedly affect Zimbra Collaboration Suite v8.5 to v8.7.11. This module was tested with Zimbra Release 8.7.1.GA.1670.UBUNTU16.64 UBUNTU16_64 FOSS edition.
