Attack-Flow Graph

Executive Summary

This vulnerability is a command injection flaw in Totolink A3002MU routers. It exists in the formWsc function of the file /boafrm/formWsc. An attacker can remotely inject malicious commands by manipulating the localPin argument. The exploit is publicly available, increasing the risk of attacks.

Detection Guidance

To detect this vulnerability, scan for Totolink A3002MU devices with firmware version Hh-B20211125.1046. Check for exposed /boafrm/formWsc endpoints and test if the localPin parameter allows command injection. Use network scanners like Nmap to identify vulnerable devices.

Impact Analysis

This vulnerability allows remote attackers to execute arbitrary commands on your router. This could lead to unauthorized access, data theft, or disruption of network services. Since the exploit is public, the risk of being targeted is higher.

Compliance Impact

This vulnerability allows remote command injection via manipulation of the localPin argument in the formWsc function. Such unauthorized remote access could lead to data breaches, unauthorized data access, or data exfiltration, which are critical violations under GDPR and HIPAA. Compliance with these regulations requires protecting against such vulnerabilities to ensure confidentiality, integrity, and availability of sensitive data.

Mitigation Strategies

Immediately update the Totolink A3002MU firmware to the latest version. Disable remote access to the router's web interface if not required. Monitor network traffic for unusual activity targeting the /boafrm/formWsc endpoint.
