|
info:
|
|
name: D-Link Routers - Remote Code Execution
|
|
author: dwisiswant0
|
|
severity: critical
|
|
description: D-Link products such as DIR-655C, DIR-866L, DIR-652, and DHP-1565 contain an unauthenticated remote code execution vulnerability. The issue occurs when the attacker sends an arbitrary input to a "PingTest" device common gateway interface that could lead to common injection. An attacker who successfully triggers the command injection could achieve full system compromise. Later, it was independently found that these issues also affected; DIR-855L, DAP-1533, DIR-862L, DIR-615, DIR-835, and DIR-825.
|
|
impact: |
|
|
Successful exploitation of this vulnerability allows an attacker to execute arbitrary code on the affected router, potentially leading to complete compromise of the device and the network it is connected to.
|
|
remediation: |
|
|
Apply the latest firmware update provided by D-Link to mitigate this vulnerability.
