Lifecycle Timeline
4DescriptionNVD
A buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 due to inadequate validation of input size in the routes_static parameter in the /router.asp endpoint.
AnalysisAI
Buffer overflow in D-Link DI-8003 router firmware 16.07.26A1 enables unauthenticated remote denial-of-service attacks via malformed routes_static parameter to /router.asp endpoint. The vulnerability permits network-accessible attackers to crash the device without credentials or user interaction. No public exploit identified at time of analysis. CVSS 7.5 (High) reflects complete availability impact with network attack vector and low complexity.
Technical ContextAI
CWE-120 classic buffer overflow stems from missing input size validation on routes_static parameter in router configuration interface. Unbounded copy operation allows oversized input to corrupt stack/heap memory, triggering crash conditions. Network-accessible endpoint accepts unauthenticated requests (PR:N), enabling trivial exploitation without authentication bypass.
RemediationAI
No vendor-released patch identified at time of analysis. Monitor D-Link security bulletin portal at https://www.dlink.com/en/security-bulletin/ for firmware updates addressing CVE-2025-50650. Immediate mitigation: restrict administrative interface access to trusted management networks via firewall rules, blocking external access to /router.asp and related configuration endpoints. Disable remote management features if not operationally required. Deploy network segmentation to isolate affected devices from untrusted networks. Consider replacing device if vendor discontinues support or delays patching beyond organizational risk tolerance thresholds.
