Publication date: 2025-09-03

Last updated on: 2025-09-09

Assigner: MITRE

Description
An OS command injection vulnerability exists in PLDT WiFi Router's Prolink PGN6401V Firmware 8.1.2 web management interface. The ping6.asp page submits user input to the /boaform/formPing6 endpoint via the pingAddr parameter, which is not properly sanitized. An authenticated attacker can exploit this flaw by injecting arbitrary system commands, which are executed by the underlying operating system with root privileges. The router uses the Boa web server (version 0.93.15) to handle the request. Successful exploitation can lead to full system compromise and unauthorized control of the network device.

Executive Summary

This vulnerability is an OS command injection in the PLDT WiFi Router Prolink PGN6401V Firmware 8.1.2. It occurs because the ping6.asp page accepts user input through the pingAddr parameter without proper sanitization. An authenticated attacker can inject arbitrary system commands that the router's operating system executes with root privileges, potentially compromising the entire system.

Impact Analysis

Exploiting this vulnerability can lead to full system compromise of the affected router, allowing an attacker to gain unauthorized control over the network device. This can result in disruption of network services, interception or manipulation of network traffic, and potential further attacks on connected devices.
