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 Adversary-in-the-Middle (T1557); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-17 (Public Key Infrastructure Certificates) and SC-23 (Session Authenticity) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

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.
