What is CVE-2017-14419?

The D-Link DIR-850L routers—specifically REV. A and REV. B with certain firmware versions—are vulnerable due to their NPAPI extension, which establishes a TCP relay for HTTP connections while also exposing a separate relay for HTTPS. This configuration can lead to potential security risks as it may allow unauthorized access to sensitive information sent through the mydlink Cloud Services, emphasizing the need for vigilance in network security practices.
