AI Analysis
Technical Summary
This vulnerability affects the D-Link DIR-816 router firmware version 1.10CNB05_R1B011D88210. It arises from improper input handling in the sub_445E7C function within the /goform/formDMZ.cgi endpoint, enabling remote command injection. The vulnerability allows an attacker to remotely execute arbitrary commands on the affected device. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and low impact on confidentiality, integrity, and availability. No official remediation or patch is currently documented.
Potential Impact
Successful exploitation of this vulnerability could allow an unauthenticated remote attacker to execute arbitrary commands on the affected router, potentially leading to unauthorized control or disruption of the device. The impact is rated medium based on the CVSS score of 5.3. There are no reports of active exploitation in the wild so far.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider limiting remote access to the affected device and monitor for unusual activity. Avoid exposing the management interface to untrusted networks. Follow vendor channels for updates on patches or official mitigations.
