Summary

CVE-2024-23943 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Vde (inferred from references). Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 37.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and IA-8 (Identification and Authentication (Non-organizational Users)).

Deeper analysis

CVE-2024-23943 is a high-severity vulnerability stemming from a lack of authentication for a critical function in affected devices, classified under CWE-306 (Missing Authentication for Critical Function). This flaw enables unauthenticated remote attackers to gain access to the cloud API. The vulnerability carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating high impacts on confidentiality and integrity but no effect on availability. It was published on 2025-03-18.

An unauthenticated remote attacker can exploit this vulnerability over the network with low attack complexity and no user interaction or privileges required. Successful exploitation provides unauthorized access to the cloud API, allowing potential compromise of sensitive data and manipulation of API functions.

Mitigation details are outlined in the VDE CERT advisory available at https://cert.vde.com/en/advisories/VDE-2024-010.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly addresses missing authentication for critical functions by requiring identification of such functions, risk assessment, and restriction or monitoring of unauthenticated access to the cloud API.

prevent

Mandates unique identification and authentication of system services, directly mitigating unauthenticated access to the vulnerable cloud API function.

prevent

Requires identification and authentication for non-organizational users, preventing unauthenticated remote attackers from exploiting the cloud API.
