CVE-2024-54847Network attack vector

Sensitive-data disclosure via exposed Diffie-Hellman parameters

Published Jan 10, 2025 · Updated Jan 13, 2025

Improper certificate validation in CP Plus CP-VNR-3104 firmware B3223P22C02424 allows remote attackers to read sensitive data over a network. Public records identify exposed Diffie-Hellman parameters but do not disclose the affected TLS locus or the validation operation that mishandles them. Exploitation requires no authentication or user interaction, has high complexity, and exposes confidentiality or enables a man-in-the-middle position.
