Executive Summary

This is an information disclosure vulnerability in MBS-Solutions X-Serie Gateway firmware V6_00_05. The ugw-deviceinfo method in /cgi-bin/wwwugw.cgi exposes detailed system version details like operatingsystem and gatewayversion to any authenticated user, even those with low-privileged Standard role access.

Detection Guidance

To detect this vulnerability, check if unauthenticated or low-privileged users can access the ugw-deviceinfo method via /cgi-bin/wwwugw.cgi. Use curl to query the endpoint: curl -k 'http://<target-ip>/cgi-bin/wwwugw.cgi?ugw-deviceinfo'. If it returns system version details without proper authentication, the system is vulnerable.

Impact Analysis

An attacker with even basic access could retrieve sensitive system information, potentially aiding further attacks by understanding the gateway's software environment and version details.

Mitigation Strategies

Immediately restrict access to the /cgi-bin/wwwugw.cgi endpoint. Update the gateway firmware to the latest version if available. Implement strict authentication and authorization checks for all CGI methods. Monitor network traffic for unauthorized access attempts to this endpoint.
