Detailsinfo

A vulnerability classified as critical was found in D-Link DIR-878 1.12A1 (Router Operating System). Affected by this vulnerability is the function SetStaticRouteIPv4Settings of the file /HNAP1 of the component HNAP API. The manipulation of the argument Gateway with an unknown input leads to a command injection vulnerability. The CWE definition for the vulnerability is CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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 SetStaticRouteIPv4Settings API function, as demonstrated by shell metacharacters in the Gateway field.
