CISA Flags Active D-Link & Array Networks Vulnerabilities in 2025 KEV Catalog
In December 2025, the Cybersecurity and Infrastructure Security Agency (CISA) expanded its Known Exploited Vulnerabilities (KEV) Catalog to include two actively exploited vulnerabilities: CVE-2022-37055, a buffer overflow in D-Link routers, and CVE-2025-66644, an OS command injection flaw impacting Array Networks ArrayOS AG. These vulnerabilities provide attack vectors for cybercriminals to gain unauthorized access, conduct lateral movement, or exfiltrate sensitive data within federal and private sector networks. The directive mandates that all Federal Civilian Executive Branch (FCEB) agencies address these threats promptly to reduce risk exposure and protect operational integrity. This update underscores the persistent threat posed by unpatched network infrastructure vulnerabilities, which remain prime targets for attackers. Timely remediation of KEV-listed vulnerabilities is increasingly critical for all organizations amid a rising trend of targeted attacks against widely deployed network devices.
