CVE-2019-20216 is a critical OS command injection vulnerability affecting D-Link DIR-859 routers running firmware versions 1.05 and 1.06B01 Beta01. Attackers can exploit this by sending a crafted M-SEARCH request to the ssdpcgi() function, leveraging mishandling of the REMOTE_PORT value to inject arbitrary commands. This vulnerability carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. While no public exploit code or active exploitation has been observed, and community discussion is minimal, the high FAUCET Risk Score of 85/100 indicates significant potential risk.
