CVE-2018-6530
CriticalCVSS 9.8KEVSummary
An OS command injection vulnerability in soap.cgi (soapcgi_main in cgibin) in D-Link DIR-880L, DIR-868L, DIR-865L, and DIR-860L routers in specific firmware versions allows remote attackers to execute arbitrary OS commands via the service parameter.
Risk Assessment
An attacker can remotely execute arbitrary OS commands on the router, leading to full device compromise and potential use as an entry point into the internal network.
Recommendation
Update the D-Link router firmware to a version newer than those listed (1.08B04, 112b04, 1.08.B01, 110b04) or disable remote access to the web interface.
