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…

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

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.
