CVE-2025-41742, published on 2025-12-02, is a critical vulnerability in Sprecher Automations' SPRECON-E-C, SPRECON-E-P, and SPRECON-E-T3 products. It stems from the use of default cryptographic keys, enabling unauthorized access. The issue carries a CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-1394.
An unauthorized remote attacker can exploit this vulnerability over the network with low complexity and no required privileges or user interaction. Successful exploitation allows the attacker to read, modify, and write projects and data, as well as access any device via remote maintenance, potentially leading to full compromise of confidentiality, integrity, and availability.
The vendor has issued a security advisory providing details on mitigation, available at https://www.sprecher-automation.com/fileadmin/itSecurity/PDF/SPR-2511042_de.pdf.

Cryptographic key establishment and management requires generating and provisioning unique keys rather than relying on manufacturer defaults.
Requiring the most restrictive configuration settings prohibits the use of known default cryptographic keys.

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.
Configuration management directly prohibits default keys via hardened baselines and change control.
Credential/key management practices eliminate default cryptographic keys for identities and services.
Strong authentication requirements implicitly disallow default keys but do not address key management itself.

Mandates proper key management, directly preventing use of default cryptographic keys.
Enforces secure configuration baselines that should replace default keys.
Controls software installation and configuration, reducing risk of default keys being left in place.
Change-management processes should detect and remediate default cryptographic keys.
Requires secure authentication mechanisms that would be undermined by default keys.
