Description

An unauthenticated command injection vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin. The vulnerability occurs in the 'SetDMZSettings' functionality, where the 'IPAddress' parameter in prog.cgi is stored in NVRAM and later used by librcm.so to construct iptables commands executed via twsystem(). An attacker can exploit this vulnerability remotely without authentication by sending a specially crafted HTTP request, leading to arbitrary command execution on the device.

Attack-Flow Graph

Impact Analysis

An attacker exploiting this vulnerability can execute arbitrary commands on the affected router remotely without authentication. This could lead to full control over the device, allowing the attacker to disrupt network traffic, intercept data, or use the device as a foothold for further attacks within the network.

Executive Summary

This vulnerability is an unauthenticated command injection in the D-Link DIR-878A1 router firmware. It occurs in the 'SetDMZSettings' function where the 'IPAddress' parameter is stored in NVRAM and later used to build iptables commands executed by the system. An attacker can exploit this remotely by sending a specially crafted HTTP request, allowing them to execute arbitrary commands on the device without needing to authenticate.
