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

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…

An arbitrary file upload vulnerability in /cgi-bin/ugwupload.cgi of MBS-Solutions X-Serie Gateway firmware V6_00_05 allows a remote authenticated user with Admin role to upload files with arbitrary content to hardcoded paths.

Insecure Permission vulnerability in MBS-Solutions X-Serie Gateway firmware V6_00_05 allows the low-privileged service user to execute /usr/bin/tcpdump as root without a password. By leveraging the tcpdump -z option, an authenticated attacker can achieve arbitrary command…

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.

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

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

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

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.

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.

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

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

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.

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

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.

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 unauthenticated remote attacker can obtain valid session tokens because they are exposed in plaintext within the URL parameters of the wwwupdate.cgi endpoint in UBR.

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.

An issue in /cgi-bin/wwwugw.cgi of MBS-Solutions X-Serie Gateway firmware V6_00_05 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…

An arbitrary file read vulnerability in /cgi-bin/ugwdownload.cgi of MBS-Solutions X-Serie Gateway firmware V6_00_05 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 information disclosure vulnerability in the ugw-deviceinfo method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware V6_00_05 returns detailed system version fields (operatingsystem, gatewayversion) to any authenticated user, including users with the…

An information disclosure vulnerability in the opcua-configuration method of /cgi-bin/wwwugw.cgi in MBS-Solutions X-Serie Gateway firmware V6_00_05 allows any remote authenticated user, including users with the low-privileged Standard role, to retrieve the configured OPC-UA…

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.

A low-privileged remote attacker can exploit the ubr-logread method in wwwubr.cgi to read arbitrary files on the system. The endpoint accepts a parameter specifying the log file to open (e.g., /tmp/weblog{some_number}), but this parameter is not properly validated, allowing an…

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

An issue in the ugw-editfile 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 write arbitrary content to files within /uxx/config/ and /ugw/config/.

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.

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…

A broken access control vulnerability in the ugw-usr-edit 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 change the password of arbitrary accounts.
