CISA KEV Advisory

D-Link Routers Buffer Overflow Vulnerability

Added to KEV: 2025-12-08Federal patch deadline: 2025-12-29

Required Action (CISA)

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Risk Analysis

This critical buffer overflow vulnerability in D-Link Routers has a high impact on confidentiality, integrity, and availability. With a CVSS score of 9.8 and an EPSS score of 0.69755, coupled with its presence in CISA's KEV, this flaw is actively exploited and poses an extreme risk.

This vulnerability is actively exploited in the wild. It is remotely exploitable (AV:N, AC:L, PR:N, UI:N) without authentication or user interaction, making it highly dangerous.

Recommended Action

Users should immediately discontinue the utilization of affected D-Link Router products, as many may be end-of-life. Replace vulnerable devices with supported and patched alternatives.

Technical Analysis

CVE-2022-37055 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

CISA has added CVE-2022-37055 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
