CVE-2024-54849 Details
Description
An issue in CP Plus CP-VNR-3104 B3223P22C02424 allows attackers to obtain the second RSA private key and access sensitive data or execute a man-in-the-middle attack.
A vulnerability exists in the CP Plus CP-VNR-3104 model, specifically in the firmware version B3223P22C02424. This issue allows attackers to exploit a timing discrepancy in the device's encryption process, particularly within the Elliptic Curve mathematics library. By observing the timing of multiple deterministic ECDSA signature generations, an attacker can extract the second RSA private key. This key extraction could lead to unauthorized access to sensitive information or facilitate a man-in-the-middle attack.
