AnalysisAIv1 – Mar 12, 2026

D-Link DIR-605L and DIR-619L routers expose sensitive information through the DHCP Connection Status Handler via unauthenticated network requests, with public exploit code available. Affected devices running firmware versions 2.06B01 and 2.13B01 can leak configuration data to remote attackers without authentication, though impact is limited to information disclosure. No patch is available as these router models are end-of-life and no longer supported by D-Link.
