An information disclosure vulnerability in the ugw-deviceinfo method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware V60005 returns detailed system version fields (operatingsystem, gatewayversion) to any authenticated user, including users with the low-privileged Standard role.

An information disclosure vulnerability in the opcua-configuration method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware V60005 allows any remote authenticated user, including users with the low-privileged Standard role, to retrieve the configured OPC-UA authentication credentials in cleartext via the JSON API response.

An arbitrary file read vulnerability in /cgi-bin/ugwdownload.cgi of MBS-Solutions X-Serie Gateway firmware V60005 allows a remote authenticated user with the low-privileged Standard role to retrieve arbitrary files from the device filesystem via the file query string parameter.

An issue in /cgi-bin/wwwugw.cgi of MBS-Solutions X-Serie Gateway firmware V60005 allows a remote authenticated user with the low-privileged Standard role to invoke hidden network diagnostic methods (ugw-ping, ugw-traceroute) that are not exposed in the web UI, allowing attackers to obtain sensitive information.

A broken access control vulnerability in the ugw-usr-edit method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware V60005 allows a remote authenticated user with the low-privileged Standard role to change the password of arbitrary accounts.

An arbitrary file upload vulnerability in /cgi-bin/ugwupload.cgi of MBS-Solutions X-Serie Gateway firmware V60005 allows a remote authenticated user with Admin role to upload files with arbitrary content to hardcoded paths.

An issue in the ugw-restart method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware V60005 allows a remote authenticated user with the low-privileged Standard role to inject arbitrary code into the dpcheck system utility executed as root.

The ugw-logread method allows a remote attacker with user privileges to access arbitrary local files due to insufficient validation of user-supplied input.

The ugw-logstop method allows a remote attacker with user privileges to terminate arbitrary processes due to insufficient validation of user-supplied input.

An unauthenticated remote attacker can recover a default, hard coded password from a firmware image and thus gain full access to all affected devices.

A remote attacker with user privileges can exploit a stack buffer overflow in dali-devconfig to gain full system access as root.

The bac-scanresult method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input.

The ugw-restore method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input.

The ugw-restoreinfo method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input.

A remote attacker with user privileges can exploit a stack buffer overflow to gain full system access as root.

The ugw-delete-file method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input.

A remote attacker with user privileges can exploit a stack buffer overflow in gdv-serverconfig to gain full system access as root.

The ugw-logstop method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input.

A high-privileged remote attacker can fully compromise the device by abusing an update signature bypass vulnerability in the wwwupdate.cgi method in the web interface of UBR.

A low-privileged remote attacker can trigger a stack-based buffer overflow via a crafted HTTP POST request using the ubr-network method resulting in full device compromise.

Due to insufficient authorization enforcement, an unauthorized remote attacker can exploit the wwwupload.cgi endpoint to upload and apply arbitrary data. This includes, but is not limited to, contact images, HTTPS certificates, system backups for restoration, server peer configurations, and BACnet/SC server certificates and keys.

Due to insufficient authorization enforcement, an unauthorized remote attacker can exploit the wwwupdate.cgi endpoint to upload and apply arbitrary updates.

A low‑privileged remote attacker can directly interact with the wwwdnload.cgi endpoint to download any resource available to administrators, including system backups and certificate request files.

An unauthenticated attacker can abuse the weak hash of the backup generated by the wwwdnload.cgi endpoint to gain unauthorized access to sensitive data, including password hashes and certificates.

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.

An administrator may attempt to block all traffic by configuring a pass filter with an empty table. However, in UBR, an empty list does not enforce any restrictions and allows all network traffic to pass unfiltered.

An administrator may attempt to block all networks by specifying "\" or "all" as the network identifier. However, these values are not supported and do not trigger any validation error. Instead, they are silently interpreted as network 0 which results in no networks being blocked at all.

A low-privileged remote attacker can exploit an arbitrary file write vulnerability in the wwupload.cgi endpoint. Due to path traversal this can lead to overwriting arbitrary files on the device and achieving a full system compromise.

A low-privileged remote attacker can abuse the backup restore functionality of UBR (ubr-restore) which runs with elevated privileges and does not validate the contents of the backup archive to create or overwrite arbitrary files anywhere on the system.

A low-privileged remote attacker can exploit the ubr-editfile method in wwwubr.cgi, an undocumented and unused API endpoint to write arbitrary files on the system.
