Summary

CVE-2024-54848 is a high-severity Improper Certificate Validation (CWE-295) vulnerability in Cpplusworld Cp-Vnr-3104 Firmware. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Private Keys (T1552.004); ranked in the top 49.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SC-17 (Public Key Infrastructure Certificates) and SC-23 (Session Authenticity).

Threat & Defense at a Glance

What attackers do: exploitation maps to Private Keys (T1552.004) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-17 Public Key Infrastructure Certificates good match

prevent

SC-17 mandates the proper selection, validation, revocation, and management of PKI certificates, directly addressing the improper handling and storage that enables decryption or MITM attacks in this CVE.

SC-23 Session Authenticity good match

prevent

SC-23 requires mechanisms to protect communications session authenticity, preventing man-in-the-middle attacks exploiting the certificate vulnerability.

SC-8 Transmission Confidentiality and Integrity good match

prevent

SC-8 enforces confidentiality and integrity protections for transmitted information, mitigating decryption of communications due to flawed certificate handling.

MITRE ATT&CK Enterprise TechniquesAI

T1552.004 Private Keys Credential Access

Adversaries may search for private key certificate files on compromised systems for insecurely stored credentials.

T1557 Adversary-in-the-Middle Credential Access

Adversaries may attempt to position themselves between two or more networked devices using an adversary-in-the-middle (AiTM) technique to support follow-on behaviors such as [Network Sniffing](https://attack.

Why these techniques?

Improper certificate handling and storage enables access to private keys (T1552.004) for decryption and facilitates man-in-the-middle attacks (T1557).

NVD Description

Improper handling and storage of certificates in CP Plus CP-VNR-3104 B3223P22C02424 allow attackers to decrypt communications or execute a man-in-the-middle attacks.

Deeper analysisAI

CVE-2024-54848 is a vulnerability stemming from improper handling and storage of certificates in the CP Plus CP-VNR-3104 network video recorder running firmware version B3223P22C02424. This issue, mapped to CWE-295 (Improper Certificate Validation), enables potential decryption of communications and carries a CVSS v3.1 base score of 7.4 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating high severity due to significant confidentiality and integrity impacts.

Remote network-based attackers with no required privileges or user interaction can exploit this vulnerability, though it demands high attack complexity. Exploitation allows adversaries to decrypt protected communications or perform man-in-the-middle attacks, compromising the secrecy and integrity of data transmitted to or from the affected device.
