2DescriptionCVE.org
A vulnerability has been found in D-Link DIR-816 1.10CNB05 and classified as critical. Affected by this vulnerability is the function qosClassifier of the file /goform/qosClassifier. The manipulation of the argument dip_address/sip_address leads to os command injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.
Executive ViewAI
D-Link DIR-816 routers running firmware 1.10CNB05 contain a critical remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary commands. Organizations using this end-of-life device face immediate risk of network compromise, unauthorized access, and potential lateral movement into corporate systems.
Implement network access controls restricting access to the affected device's web interface; disable QoS features if operationally feasible; deploy WAF/IDS rules to block malicious payloads targeting /goform/qosClassifier endpoint; segment affected devices behind firewall rules limiting their network exposure; consider disabling remote management access; monitor for suspicious activity on affected devices.
Threat Intelligence Overview
How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
OS command injection occurs when an application passes unsanitized user input directly into system shell commands.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
