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_group.asp endpoint.

AnalysisAI

Buffer overflow in D-Link DI-8003 router firmware 16.07.26A1 enables unauthenticated remote denial-of-service attacks via crafted name parameter to /url_group.asp endpoint. Attackers can trigger stack-based buffer overflow remotely over network without user interaction, causing high availability impact through service disruption or device crash. No public exploit identified at time of analysis. CVSS 7.5 severity reflects network-accessible attack vector with low complexity.

Technical ContextAI

Stack-based buffer overflow (CWE-121) in /url_group.asp endpoint lacks input validation on name parameter length. Improper bounds checking allows oversized input to corrupt stack memory, triggering denial-of-service condition. Attack requires no authentication (PR:N) and exploits web management interface directly accessible over network.

RemediationAI

No vendor-released patch identified at time of analysis. D-Link has not published specific security advisory addressing CVE-2025-50662 for DI-8003 16.07.26A1 firmware. Recommended immediate mitigations: restrict web management interface access to trusted internal networks only via firewall rules, disable remote administration if not operationally required, implement network segmentation isolating device from untrusted networks. Monitor D-Link security bulletin portal at https://www.dlink.com/en/security-bulletin/ for future firmware updates. Consider hardware replacement if device reaches end-of-support lifecycle. Low observed exploitation activity (EPSS <1%) suggests limited active targeting currently.
