Assigner: MITRE

Description
A command injection vulnerability in COMFAST CF-XR11 (firmware V2.7.2) exists in the multi_pppoe API, processed by the sub_423930 function in /usr/bin/webmgnt. The phy_interface parameter is not sanitized, allowing attackers to inject arbitrary commands via a POST request to /cgi-bin/mbox-config?method=SET&section=multi_pppoe. When the action parameter is set to "one_click_redial", the unsanitized phy_interface is used in a system() call, enabling execution of malicious commands. This can lead to unauthorized access to sensitive files, execution of arbitrary code, or full device compromise.

Executive Summary

This vulnerability is a command injection flaw in the COMFAST CF-XR11 router firmware version 2.7.2. It occurs in the multi_pppoe API where the phy_interface parameter is not properly sanitized. An attacker can send a specially crafted POST request to the /cgi-bin/mbox-config endpoint with the action parameter set to "one_click_redial" and inject arbitrary commands through the phy_interface parameter. These commands are executed by the system() call, allowing the attacker to run malicious code on the device.

Impact Analysis

Exploitation of this vulnerability can lead to unauthorized access to sensitive files, execution of arbitrary code, or full compromise of the affected device. This means an attacker could take control of the device, potentially disrupting network operations, stealing data, or using the device as a foothold for further attacks.
