Executive Summary

CVE-2026-52484 is a Remote Code Execution (RCE) vulnerability in the MitraStar GPT-2742GX4X5v6-SV router with firmware GL_g2.5_100XNT0b23_3. It exists in the VIVO administration portal's diagnostic tools via the /cgi-bin/device-management-utilities-internet.cgi endpoint. Authenticated attackers can exploit command injection by bypassing input sanitization using URL-encoded characters like %26%26 (equivalent to &&). This allows arbitrary command execution in the router's OS.

Detection Guidance

To detect this vulnerability, check if your MitraStar GPT-2742GX4X5v6-SV router is running firmware version GL_g2.5_100XNT0b23_3. Inspect network traffic for requests to /cgi-bin/device-management-utilities-internet.cgi with URL-encoded concatenation characters like %26%26. Monitor for unusual command execution or Telnet connections on non-standard ports.

Impact Analysis

An attacker could gain control of the router to access sensitive files, modify configurations, or escalate privileges. They could also open backdoors like a Telnet service on port 4444 for persistent access. This could lead to network compromise, data theft, or further attacks within the local network.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements and HIPAA's security rules for protected health information. Organizations may face compliance breaches, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Immediately update the router firmware to a patched version if available. Disable remote administration access to the router. Implement strict input validation by replacing blacklist sanitization with whitelist validation. Replace unsafe system() calls with safer exec-type functions in the router's firmware.
