Which versions of D-Link are affected by CVE-2025-50660?

CVE-2025-50660 is a stack-based buffer overflow affecting D-Link DI-8003 routers (firmware 16.07.26A1) that allows remote attackers to remotely crash the device and disrupt network routing services…

How to fix or mitigate CVE-2025-50660?

Within 24 hours: Identify all D-Link DI-8003 devices running firmware 16.07.26A1 in your environment using network scanning or device inventory tools; isolate or air-gap affected routers if replacement is not immediately possible. Within 7 days: Check D-Link support for firmware updates beyond 16.07.26A1 and test in a non-production environment; if no patched firmware is available, implement network segmentation to restrict access to the /url_member.asp endpoint. Within 30 days: Deploy replacement routing hardware or confirmed patched firmware versions; conduct a post-incident review if this vulnerability was exploited during the interim period.

HIGH 7.5

DescriptionCVE.org

A buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 due to improper handling of the name parameter in the /url_member.asp endpoint.

AnalysisAI

Stack-based buffer overflow in D-Link DI-8003 router firmware 16.07.26A1 allows unauthenticated remote attackers to trigger denial-of-service conditions by sending malformed name parameter values to the /url_member.asp endpoint. The vulnerability enables network-accessible attackers to crash the device without authentication or user interaction, disrupting availability of routing services. No public exploit identified at time of analysis.

Technical ContextAI

CWE-121 stack-based buffer overflow caused by insufficient bounds checking on the name parameter in /url_member.asp. The firmware fails to validate input length before copying data to a fixed-size stack buffer, allowing oversized values to corrupt adjacent memory regions and destabilize the web management interface.

RemediationAI

No vendor-released patch identified at time of analysis. Consult D-Link security bulletin at https://www.dlink.com/en/security-bulletin/ for official remediation guidance. Until patched firmware becomes available, restrict network access to the web management interface (/url_member.asp) through firewall rules permitting only trusted administrator IP addresses. Disable remote management features if not operationally required. Consider deploying network segmentation to isolate affected routers from untrusted networks. Monitor D-Link support channels for firmware updates addressing CVE-2025-50660. Contact D-Link technical support directly for enterprise deployment guidance.
