CVE-2019-8317
This issue is a Command Injection allowing a remote attacker to execute arbitrary code, and get a root shell.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered on D-Link DIR-878 devices with firmware 1.12A1. This issue is a Command Injection allowing a remote attacker to execute arbitrary code, and get a root shell. A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted /HNAP1 POST request. This occurs when any HNAP API function triggers a call to the system function with untrusted input from the request body for the SetStaticRouteIPv6Settings API function, as demonstrated by shell metacharacters in the DestNetwork field.
