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 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.

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.
