On D-Link DAP-1530 (A1) before firmware version 1.06b01, DAP-1610 (A1) before firmware version 1.06b01, DWR-111 (A1) before firmware version 1.02v02, DWR-116 (A1) before firmware version 1.06b03, DWR-512 (B1) before firmware version 2.02b01, DWR-711 (A1) through firmware version 1.11, DWR-712 (B1) before firmware version 2.04b01, DWR-921 (A1) before firmware version 1.02b01, and DWR-921 (B1) before firmware version 2.03b01, there exists an EXCU_SHELL file in the web directory. By sending a GET request with specially crafted headers to the /EXCU_SHELL URI, an attacker could execute arbitrary shell commands in the root context on the affected device. Other devices might be affected as well.
This vulnerability carries a CRITICAL severity rating with a CVSS v3.1 score of 9.8, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 17 products from d-link, from dlink, from d-link and 14 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2019, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For d-link's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
