An issue in the ugw-restart method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware V6_00_05 allows a remote authenticated user with the low-privileged Standard role to inject arbitrary code into the dpcheck system utility executed as root.
AnalysisAI
Command injection in MBS-Solutions X-Serie Gateway firmware V6_00_05 enables an authenticated low-privileged Standard-role user to execute arbitrary OS commands as root by exploiting the ugw-restart method in /cgi-bin/wwwugw.cgi. Unsanitized user input is passed directly to the dpcheck system utility, which runs with root privileges, yielding full device compromise from a minimal trust level. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Standard-role (low-privilege) user account on the MBS-Solutions X-Serie Gateway - unauthenticated exploitation is not possible per CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) is consistent with the described exploitation path: a network-reachable CGI endpoint requiring only a Standard-role account with no complexity barriers, yielding full C/I/A impact via root-level command execution. … 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 with a confirmed fixed firmware version has been identified in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, restrict network access to affected gateways' management interfaces to trusted administrative networks only and audit user access logs for any suspicious activity. …
