Command Injection in Multiple Snap One Araknis Networks Products

Overview

Multiple Snap One Araknis Networks products are vulnerable to authenticated command injection attacks within their administrative panels. This vulnerability can be triggered by sending specially crafted HTTP requests to affected models’ onboard, web-based networking tools. Exploiting these vulnerabilities allows the attacker to fully takeover the devices as the root user and may be leveraged via Cross-Site Request Forgery (CSRF).  

Remediation

Firmware updates may be obtained through Snap One Partners or from the Snap One Product Support section.
