CVE-2025-30095 describes a critical vulnerability in VyOS 1.3 through 1.5 and other Debian-based systems using Dropbear with live-build, where identical SSH host keys are distributed across installations, enabling active man-in-the-middle attacks. With a CVSS score of 9.0 (CRITICAL), this network-based vulnerability has high impact on confidentiality, integrity, and availability, despite requiring high attack complexity. While not actively exploited or having public exploit code, its widespread potential in Debian-based systems warrants immediate mitigation by regenerating Dropbear keys or updating to VyOS 1.4.2 or later.
