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.

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 arbitra…

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 low‑privileged local attacker who gains access to the UBR service account (e.g., via SSH) can escalate privileges to obtain full system access.

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 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 exploit the ubr-editfile method in wwwubr.cgi, an undocumented and unused API endpoint to read arbitrary files on the system.

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.
