Single-A: External Control of File Name or Path
The bac-scanresult method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input.
- 9.8 Critical severity
Single-A: Use of Default Password
An unauthenticated remote attacker can recover a default, hard coded password from a firmware image and thus gain full access to all affected devices.
- 7.5 High severity
UBR-01 Mk II: Use of HTTP Request With Sensitive Query String
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.
- 7.2 High severity
UBR-01 Mk II: Improper Verification of Cryptographic Signature
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.
- 8.8 High severity
UBR-01 Mk II: Out-of-bounds Write
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.
- 9.1 Critical severity
UBR-01 Mk II: Missing Authorization
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,
- 9.1 Critical severity
UBR-01 Mk II: Missing Authorization
Due to insufficient authorization enforcement, an unauthorized remote attacker can exploit the wwwupdate.cgi endpoint to upload and apply arbitrary updates.
- 7.8 High severity
UBR-01 Mk II: Improper Neutralization of Argument Delimiters in a Command
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.
- 8.8 High severity
UBR-01 Mk II: Improper Limitation of a Pathname to a Restricted Directory
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.
- 8.8 High severity
UBR-01 Mk II: Improper Limitation of a Pathname to a Restricted Directory
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.
- 8.1 High severity
UBR-01 Mk II: Inclusion of Undocumented Features or Chicken Bits
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.
