Deck Mate 2 is distributed with static, hard-coded credentials for the root shell and web user interface, while multiple management services (SSH, HTTP, Telnet, SMB, X11) are enabled by default. If an attacker can reach these interfaces - most often through local or near-local access such as connecting to the USB or Ethernet ports beneath the table - the built-in credentials permit administrative login and full control of the system. Once authenticated, an attacker can access firmware utilities, modify controller software, and establish persistent compromise. Remote attack paths via network, cellular, or telemetry links may exist in specific configurations but generally require additional capabilities or operator error. The vendor reports that USB access has been disabled in current firmware builds.
Weakness
The product contains hard-coded credentials, such as a password or cryptographic key.
Extended Description
There are two main variations:
Potential Mitigations
- For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible [REF-7].
- In Windows environments, the Encrypted File System (EFS) may provide some protection.
- For inbound authentication using passwords: apply strong one-way hashes to passwords and store those hashes in a configuration file or database with appropriate access control. That way, theft of the file/database still requires the attacker to try to crack the password. When handling an incoming password during authentication, take the hash of the password and compare it to the saved hash.
- Use randomly assigned salts for each separate hash that is generated. This increases the amount of computation that an attacker needs to conduct a brute-force attack, possibly limiting the effectiveness of the rainbow table method.
- For front-end to back-end connections: Three solutions are possible, although none are complete.
