CVE-2024-54846 identifies a cryptographic vulnerability in the CP Plus CP-VNR-3104 B3223P22C02424 security camera device. The flaw allows attackers to extract the elliptic curve (EC) private key used by the device for secure communications. Possession of this private key enables attackers to decrypt sensitive data streams or impersonate the device in man-in-the-middle (MitM) attacks, compromising confidentiality. The vulnerability stems from improper certificate validation or key management practices, classified under CWE-295 (Improper Certificate Validation). The CVSS v3.1 vector (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N) indicates the attack can be performed remotely over the network without privileges or user interaction but requires high attack complexity, possibly due to the need for advanced cryptanalysis or physical access to extract keys. There is no impact on integrity or availability, but confidentiality is severely affected. No patches or fixes have been published yet, and no active exploits have been reported. The affected device is commonly used in surveillance and security infrastructure, making this vulnerability critical for protecting sensitive environments.

The primary impact of this vulnerability is the compromise of confidentiality. Attackers who obtain the EC private key can decrypt encrypted communications, gaining access to sensitive video feeds or device data. This can lead to privacy violations, unauthorized surveillance, or leakage of sensitive operational information. Additionally, attackers can perform man-in-the-middle attacks, intercepting and potentially manipulating data streams without detection. While integrity and availability are not directly affected, the breach of confidentiality can undermine trust in the security infrastructure and lead to broader security incidents. Organizations relying on CP Plus CP-VNR-3104 devices in critical environments such as government, corporate, or industrial sectors face increased risk of espionage or data theft. The lack of patches and known exploits suggests a window of exposure until mitigations are implemented.

1. Immediately isolate affected CP Plus CP-VNR-3104 devices from untrusted networks to reduce exposure. 2. Monitor network traffic for unusual activity indicative of MitM or unauthorized access attempts. 3. Employ network segmentation and strict firewall rules to limit device communication to trusted endpoints only. 4. Use VPNs or additional encryption layers to protect data in transit beyond the device's native encryption. 5. Contact CP Plus support for guidance and request firmware updates or patches addressing this vulnerability. 6. If possible, replace vulnerable devices with models that have verified secure key management and certificate validation. 7. Conduct regular security audits and penetration testing focusing on cryptographic implementations. 8. Educate security teams about the risks of cryptographic key exposure and implement strict key management policies. 9. Stay informed about updates from CP Plus and cybersecurity advisories for new patches or exploit reports.
