Description

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1_FW102B02 within the `prog.cgi` and `librcm.so` binaries. The `sub_4455BC` function in `prog.cgi` stores user-supplied `SetDMZSettings/IPAddress` values in NVRAM via `nvram_safe_set("dmz_ipaddr", ...)`. These values are later retrieved in the `DMZ_run` function of `librcm.so` using `nvram_safe_get` and concatenated into `iptables` shell commands executed via `twsystem()` without any sanitization. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.

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.

Attack-Flow Graph

Executive Summary

This vulnerability is a command injection flaw in the D-Link DIR-882 Router firmware. It occurs because user-supplied IP address values for DMZ settings are stored without proper sanitization and later used in shell commands executed by the router. An unauthenticated remote attacker can send specially crafted HTTP requests to the router's web interface to execute arbitrary commands on the device.

Impact Analysis

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