An information disclosure vulnerability in the ugw-deviceinfo method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware V6_00_05 returns detailed system version fields (operatingsystem, gatewayversion) to any authenticated user, including users with the low-privileged Standard role.
AnalysisAI
Unauthenticated-equivalent version disclosure in MBS-Solutions X-Serie Gateway firmware V6_00_05 allows any authenticated user - including the low-privileged Standard role - to retrieve detailed system fingerprinting data via the ugw-deviceinfo method of /cgi-bin/wwwugw.cgi. The endpoint returns operatingsystem and gatewayversion fields without enforcing role-based access controls, exposing exact firmware and OS version strings that enable targeted follow-on attacks against known vulnerabilities. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid account on the X-Serie Gateway, including the lowest-privilege Standard role - unauthenticated access is not sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) is somewhat overstated on the C:H metric - leaked data is limited to OS version and gateway firmware version strings, not credentials, keys, or user data, which would normally warrant C:L. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch version is identified in the available references at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
