Deeper analysis
D-Link DIR-878 routers running firmware version 1.30B08 contain an OS command injection vulnerability (CWE-78) in the /setnetworksettings/IPAddress endpoint. The flaw permits unauthenticated attackers to supply a crafted payload that results in arbitrary command execution with root privileges, reflected in the CVSS 9.8 rating for network-accessible, low-complexity exploitation without authentication or user interaction.
Remote attackers can target the device over the network to inject and run commands, fully compromising the router and any attached network resources. Public proof-of-concept code demonstrating the injection has been published on GitHub.
D-Link has published a security bulletin addressing the issue; administrators should consult the vendor advisory for available firmware updates or configuration guidance. The EPSS score has remained steady at 0.2188 since disclosure, indicating sustained but not sharply increasing exploitation interest.
