A vulnerability was found in D-Link DIR-878 1.12A1 (Router Operating System) and classified as critical. Affected by this issue is the function SetQoSSettings of the file /HNAP1 of the component HNAP API. The manipulation of the argument IPAddress with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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 SetQoSSettings API function, as demonstrated by shell metacharacters in the IPAddress field.

The bug was discovered 02/12/2019. The weakness was released 02/13/2019. This vulnerability is handled as CVE-2019-8314 since 02/12/2019. The exploitation is known to be easy. The attack may be launched remotely. The requirement for exploitation is a simple authentication. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 07/10/2023). The MITRE ATT&CK project declares the attack technique as T1202.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
