Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-2861 is a vulnerability in the SaTECH BCU firmware version 2.1.3, where the web interface uses the HTTP protocol instead of a secure alternative. This results in the exchange of sensitive information, such as credentials, in unencrypted plaintext during web browsing sessions. Classified under CWE-319 (Cleartext Transmission of Sensitive Information), the issue 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), highlighting high confidentiality impact with network accessibility and low attack complexity.
Any attacker with access to the network traffic between a user and the affected device can exploit this vulnerability without requiring privileges or user interaction. By performing a man-in-the-middle interception, the attacker can capture transmitted credentials and subsequently log in legitimately to the SaTECH BCU, potentially gaining unauthorized access to its functions.
The INCIBE-CERT advisory at https://www.incibe.es/en/incibe-cert/notices/aviso-sci/multiple-vulnerabilities-arteches-satech-bcu details this and other vulnerabilities in Artech's SaTECH BCU, providing guidance on mitigations for affected deployments.

Specifying encryption and other security technology for network services prevents transmission of sensitive information in cleartext over potentially untrusted channels.
Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.
Specifying communications-security requirements and secure remote-access methods (including encryption expectations) prevents the transmission of sensitive data in cleartext over home or public networks.
Armoured conduits, electromagnetic shielding and locked enclosures make passive eavesdropping on unencrypted traffic traversing the cables more difficult, mitigating exposure of sensitive data in transit.
