CVE-2026-76676: Unauthenticated Buffer Overflow Vulnerabilities lead to Remote Code Execution in EdgeConnect SD-WAN Gateways
Buffer overflow vulnerabilities exist in the underlying operating system of EdgeConnect SD-WAN Gateways that could allow an unauthenticated adjacent attacker to execute arbitrary code if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system leading to complete system compromise.

Frequently Asked Questions
What network position does an attacker need?
The attacker must be adjacent to the affected gateway. The available information does not indicate that exploitation can be performed from an arbitrary remote network location.
Does exploitation require authentication or user interaction?
No authentication or user interaction is required. However, successful exploitation depends on certain preconditions that are outside the attacker’s control.
What level of access could successful exploitation provide?
An attacker could execute arbitrary code as a privileged user on the underlying operating system, potentially resulting in complete system compromise.
