Executive Summary — External Network Penetration Test

Between March 4 and March 15, our team conducted a black-box penetration test of the client's external-facing infrastructure. The engagement identified 9 findings: 2 Critical, 3 High, 3 Medium, and 1 Low. The most significant finding, an unauthenticated remote code execution vulnerability in a legacy VPN appliance, would have allowed a threat actor to gain a foothold on the internal network without valid credentials. This finding is detailed in Section 3.1 and should be remediated as a top priority before any other action items. Overall, the external attack surface reflects a moderate security posture, with several quick wins available through patch management. A full breakdown of findings, reproduction steps, and remediation guidance follows in Section 4.
