CVE-2026-75161
UnknownSummary
An issue in the ugw-restart method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware allows a remote authenticated user with the low-privileged Standard role to inject arbitrary code into the dpcheck system utility executed as root.
Risk Assessment
An attacker can execute arbitrary code as root, leading to complete compromise of the device and potentially the entire network.
Recommendation
Immediately restrict access to the ugw-restart method to administrators only and properly sanitize parameters passed to the dpcheck utility.
