Title: Ecessa WANWorx WVR-30 10.7.4 CSRF Add Superuser Exploit
Advisory ID: ZSL-2018-5475
Type: Local/Remote
Impact: Cross-Site Scripting
Risk: (3/5)
Release Date: 24.06.2018

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.

Description

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.
