CVE-2026-75161: n/a
Description
CVE-2026-75161 is a high-severity vulnerability in the MBS-Solutions X-Serie Gateway firmware V6_00_05. It allows a remote authenticated user with low-privileged Standard role access to inject arbitrary code into the dpcheck system utility, which is executed with root privileges. This vulnerability arises from an issue in the ugw-restart method of /cgi-bin/wwwugw.cgi. Exploitation could lead to full system compromise due to the root-level execution of injected code.

Technical Analysis
This vulnerability exists in the ugw-restart method of the /cgi-bin/wwwugw.cgi endpoint in MBS-Solutions X-Serie Gateway firmware version V6_00_05. A remote authenticated user with the Standard role, which is low-privileged, can inject arbitrary code into the dpcheck system utility. The dpcheck utility runs with root privileges, so successful exploitation allows execution of arbitrary commands as root. The CVSS v3.1 base score is 8.8, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with low-privileged authenticated access can execute arbitrary code as root on the affected device. This can lead to complete system compromise, including unauthorized access, data manipulation, and denial of service.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the affected endpoint to trusted users only and monitor for suspicious activity related to the ugw-restart method.
