Description

A command injection vulnerability exists in the ToToLink A720R Router firmware V4.1.5cu.614_B20230630 within the sysconf binary, specifically in the sub_40BFA4 function that handles network interface reinitialization from '/var/system/linux_vlan_reinit'. Input is only partially validated by checking the prefix of interface names, and is concatenated into shell commands executed via system() without escaping. An attacker with write access to this file can execute arbitrary commands on the device.

Attack-Flow Graph

Executive Summary

This vulnerability is a command injection flaw in the ToToLink A720R Router firmware version V4.1.5cu.614_B20230630. It occurs in the sysconf binary, specifically in the sub_40BFA4 function that manages network interface reinitialization using the file '/var/system/linux_vlan_reinit'. The input is only partially validated by checking the prefix of interface names, and then concatenated into shell commands executed via system() without proper escaping. This allows an attacker who can write to this file to 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 router. This can lead to full compromise of the device, unauthorized control, disruption of network services, data interception, or further attacks on the network.
