Details
A vulnerability, which was classified as critical, was found in MBS UBR-01 Mk II, UBR-02 and UBR-LON. Affected is some unknown functionality. The manipulation with an unknown input leads to a argument injection vulnerability. CWE is classifying the issue as CWE-88. The product constructs a string for a command to be executed by a separate component
in another control sphere, but it does not properly delimit the
intended arguments, options, or switches within that command string. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
A low‑privileged local attacker who gains access to the UBR service account (e.g., via SSH) can escalate privileges to obtain full system access. This is due to the service account being permitted to execute certain binaries (e.g., tcpdump and ip) with sudo.
