CVE-2018-20432
D-Link COVR-2600R and COVR-3902 Kit before 1.01b05Beta01 use hardcoded credentials for telnet connection, which allows unauthenticated attackers to gain privileged access to the router, and to extract sensitive data or modify the configuration.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.93%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
