Description

An unauthenticated command injection vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin. The vulnerability occurs in the 'SetDynamicDNSSettings' functionality, where the 'ServerAddress' and 'Hostname' parameters in prog.cgi are stored in NVRAM and later used by rc to construct system 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

Executive Summary

This vulnerability is an unauthenticated command injection in the D-Link DIR-878A1 router firmware. It occurs in the 'SetDynamicDNSSettings' function where certain parameters ('ServerAddress' and 'Hostname') are stored and later used to build system commands. An attacker can send a specially crafted HTTP request remotely without needing to log in, which allows them to execute arbitrary commands on the device.

Impact Analysis

The vulnerability allows a remote attacker to execute arbitrary commands on the affected router without authentication. This can lead to full compromise of the device, including unauthorized control, data theft, disruption of network services, or using the device as a foothold for further attacks.
