Summary

CVE-2024-7344 is a high-severity Improper Verification of Cryptographic Signature (CWE-347) vulnerability in Cs-Grp Neo Impact. Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Supply Chain Compromise (T1195); ranked in the top 39% 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 map to SC-13 (Cryptographic Protection) and SI-7 (Software, Firmware, and Information Integrity) — see the control section below for these in your framework.

CVE-2024-7344 is a vulnerability in the Howyar UEFI Application "Reloader," affecting both 32-bit and 64-bit versions. It enables the execution of unsigned software stored in a hardcoded path, linked to CWE-347 (Improper Verification of Signature). The issue carries a CVSS v3.1 base score of 8.2 (AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H) and was published on 2025-01-14.

A local attacker with high privileges can exploit this vulnerability with low complexity and no user interaction required. Exploitation allows execution of unsigned code in the specified path, potentially compromising confidentiality, integrity, and availability at a high level within a changed scope, such as during the UEFI boot process.

Advisories and references, including the CERT vulnerability note (https://www.kb.cert.org/vuls/id/529659), UEFI specifications on the Boot Manager (https://uefi.org/specs/UEFI/2.10/03_Boot_Manager.html) and Secure Boot and Driver Signing (https://uefi.org/specs/UEFI/2.10/32_Secure_Boot_and_Driver_Signing.html), and the UEFI revocation list file (https://uefi.org/revocationlistfile), provide context on Secure Boot mechanisms and signature verification. An ESET blog post (https://www.eset.com/blog/enterprise/preparing-for-uefi-bootkits-eset-discovery-shows-the-importance-of-cyber-intelligence/) discusses UEFI bootkit preparations and the role of cyber intelligence.

Mitigating Controls (NIST 800-53 r5) AI

Requiring cryptographic protection mechanisms forces correct signature verification to be implemented for data protection.

Mandating integrity verification tools directly requires proper cryptographic signature checking to detect unauthorized changes.

Protecting session authenticity requires correct verification of cryptographic signatures or equivalent mechanisms.
