CVE-2026-75162
UnknownSummary
An information disclosure vulnerability in the opcua-configuration method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware allows any remote authenticated user, including users with the low-privileged Standard role, to retrieve the configured OPC-UA authentication credentials in cleartext via the JSON API response.
Risk Assessment
Disclosure of OPC-UA credentials in cleartext could allow an attacker unauthorized access to industrial systems or other resources protected by those credentials.
Recommendation
Immediately restrict access to the opcua-configuration method to administrators only and encrypt or hide credentials in API responses.
