Assigner: MITRE

Description
A command injection vulnerability exists in the D-Link DIR-823G router firmware DIR823G_V1.0.2B05_20181207.bin in the timelycheck and sysconf binaries, which process the /var/system/linux_vlan_reinit file. The vulnerability occurs because content read from this file is only partially validated for a prefix and then formatted using vsnprintf() before being executed with system(), allowing an attacker with write access to /var/system/linux_vlan_reinit to execute arbitrary commands on the device.

Executive Summary

This vulnerability is a command injection flaw in the D-Link DIR-823G router firmware. It exists in the timelycheck and sysconf binaries that process the /var/system/linux_vlan_reinit file. The content of this file is only partially validated for a prefix and then formatted using vsnprintf() before being executed with system(). Because of this insufficient validation, an attacker who can write to this file can execute arbitrary commands on the device.

Impact Analysis

If exploited, this vulnerability allows an attacker with write access to the /var/system/linux_vlan_reinit file to execute arbitrary commands on the affected router. This could lead to unauthorized control over the device, potentially compromising network security, disrupting network operations, or enabling further attacks within the network.
