Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-2862 is a vulnerability in the SaTECH BCU firmware version 2.1.3, where weak password encryption is implemented, classified under CWE-261. The issue stems from storage methods that lack sufficient encryption strength, enabling credential extraction. It carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high severity due to network accessibility, low attack complexity, and no requirements for privileges or user interaction.

An unauthenticated attacker with access to the device's system or website can exploit this vulnerability to obtain stored credentials. Exploitation requires no privileges and can occur remotely over the network with low complexity, resulting in high-impact confidentiality loss without affecting integrity or availability.

The INCIBE-CERT advisory (https://www.incibe.es/en/incibe-cert/notices/aviso-sci/multiple-vulnerabilities-arteches-satech-bcu), published on 2025-03-28, addresses multiple vulnerabilities in Arteches SaTECH BCU, including CVE-2025-2862.

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.

PR.DS-01 mostly match
prevents

Proper cryptographic hashing for data-at-rest directly prevents trivial password encoding while the control addresses broader data protection needs.

prevents

Requires appropriate use of cryptography, indirectly discouraging weak encoding schemes.

degrades

Requires secure handling and protection of authentication information, directly addressing weak password encoding.

prevents

Enforces secure coding practices that would reject trivial password encoding.

degrades

Mandates secure authentication mechanisms, which precludes trivial encoding of passwords.
