CVE-2024-54849 is a cryptographic vulnerability identified in the CP Plus CP-VNR-3104 B3223P22C02424 surveillance device. The flaw allows attackers to extract a secondary RSA private key from the device, which is critical for establishing secure communications and authenticating data exchanges. This vulnerability falls under CWE-295, indicating improper certificate validation or cryptographic key management. By obtaining the RSA private key, attackers can decrypt sensitive data streams or impersonate the device in man-in-the-middle attacks, potentially intercepting or altering communications without detection. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, but the attack complexity is high, implying that a sophisticated attacker with specific knowledge or capabilities is needed to successfully exploit it. No patches or fixes have been published yet, and no active exploitation has been reported. The CVSS 3.1 base score is 5.9, reflecting medium severity with a vector indicating network attack vector, high attack complexity, no privileges required, no user interaction, unchanged scope, high confidentiality impact, and no impact on integrity or availability. This vulnerability poses a significant risk to confidentiality, particularly in environments where the device is used to secure sensitive video feeds or data transmissions.

The primary impact of CVE-2024-54849 is the compromise of confidentiality due to exposure of the RSA private key. Attackers gaining access to this key can decrypt encrypted communications, access sensitive surveillance data, or impersonate the device to conduct man-in-the-middle attacks. This undermines trust in the device’s security and can lead to unauthorized data disclosure, privacy violations, and potential manipulation of video feeds or control commands. Although integrity and availability are not directly affected, the breach of confidentiality alone can have severe consequences for organizations relying on these devices for security monitoring, especially in critical infrastructure, government facilities, or corporate environments. The high attack complexity reduces the likelihood of widespread exploitation but does not eliminate the risk to high-value targets. The absence of patches increases exposure time, necessitating immediate mitigation efforts.

Organizations should implement network segmentation to isolate CP Plus CP-VNR-3104 devices from untrusted networks and restrict access to management interfaces. Employ strong network monitoring and anomaly detection to identify unusual access patterns or attempts to extract cryptographic material. Use VPNs or additional encryption layers to protect data in transit beyond the device’s native encryption. Regularly audit device configurations and firmware versions, and subscribe to vendor advisories for patch releases. If possible, replace affected devices with models that have verified secure key management. Employ strict access controls and limit exposure of these devices to the internet or untrusted networks. Additionally, consider deploying intrusion prevention systems (IPS) tuned to detect attempts to exploit cryptographic vulnerabilities. Maintain an incident response plan to quickly address any suspected compromise involving these devices.
