| Title | Tomofun Furbo 360, Furbo Mini Furbo 360 (≤ FB0035_FW_036), Furbo Mini (≤ MC0020_FW_074) Insecure Encryption Algorithm |
|---|
| Description | The Furbo Mini device stores the root user password in `/etc/shadow` using DES-based hashing. DES (Data Encryption Standard) is a deprecated encryption method known to be cryptographically weak due to its:
- Small key size (56-bit),
- Susceptibility to brute-force attacks,
- Vulnerability to modern cryptanalysis.
Because of this weak encryption, an attacker with access to the device's filesystem (e.g., via UART or firmware extraction) can easily *brute-force the root password hash and obtain cleartext credentials using commonly available tools like Hashcat.
This allows an attacker to:
- Bypass all local authentication protections,
- Access or manipulate sensitive system data,
- Escalate privileges or modify the device’s behavior. |
