Digi International Inc.

Digi International manufactures industrial-grade cellular and networking devices—including transport and connectivity platforms such as the Transport WR series and ConnectPort line—that operate in mission-critical infrastructure and remote-access deployments where firmware and embedded software control network behavior. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity, and a meaningful tendency toward public exploit availability across its product portfolio. The recurring weakness classes, including cross-site scripting, missing authentication controls, out-of-bounds writes, dangerous file uploads, and authentication bypass mechanisms, reflect the web-management interfaces and embedded authentication challenges inherent to remotely administered edge devices. Defenders should prioritize patching exposed instances of these devices and restrict management access to trusted networks, as firmware updates for industrial and long-deployed devices often lag behind release cycles. Current exploitation activity and exposure counts are shown alongside this summary.
