Crypto Weakness in Mbconnectline Mbnet.Mini Firmware ≤ 2.3.1
Raw vector
CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2024-45273 is a high-severity Weak Encoding for Password (CWE-261) vulnerability in Mbconnectline Mbnet.Mini Firmware. Its CVSS base score is 8.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 0.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Vulnerability Data
An unauthenticated local attacker can decrypt the devices config file and therefore compromise the device due to a weak implementation of the encryption used.

Mitigating Controls (NIST 800-53 r5) AI
Cryptographic protection mandates approved algorithms and key management that preclude weak encoding schemes for sensitive data such as passwords.
Authenticator management requires secure generation, storage, and distribution of passwords rather than trivial encoding.
SC-12 governs cryptographic key establishment and management, which can enforce sufficient key sizes and thereby reduce inadequate encryption strength.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Proper cryptographic hashing for data-at-rest directly prevents trivial password encoding while the control addresses broader data protection needs.
Strong encryption is required to protect confidentiality of data-in-transit.
Hardened baselines can enforce minimum cryptographic algorithm and key-length settings.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Requires appropriate use of cryptography, indirectly discouraging weak encoding schemes.
Requires secure handling and protection of authentication information, directly addressing weak password encoding.
Enforces secure coding practices that would reject trivial password encoding.
Mandates secure authentication mechanisms, which precludes trivial encoding of passwords.
