Summary

CVE-2024-20678 is a high-severity Type Confusion (CWE-843) vulnerability in Microsoft Windows 10 1507. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 17% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

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

CVE-2024-20678 is a Remote Procedure Call Runtime Remote Code Execution Vulnerability affecting the RPC runtime component in Microsoft systems. It carries a CVSS 3.1 score of 8.8 with the vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H and is also associated with CWE-843.

An attacker with low privileges can exploit the flaw remotely over a network connection without user interaction, achieving arbitrary code execution that fully compromises confidentiality, integrity, and availability on the target system.

Microsoft publishes mitigation guidance and patch information for this issue in its Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-20678. The EPSS score has remained flat at a peak and current value of 0.0708 with no material increase observed after disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including fuzzing and type-aware analysis) directly finds type-confusion flaws before deployment.

Engineering principles can require use of type-safe languages, static typing, and runtime type checks that structurally avoid allocating one type and accessing another.

Memory-protection controls limit the blast radius when a type-confusion access occurs but do not stop the flaw itself.

finds

Security testing in development can detect type-confusion vulnerabilities through fuzzing and static analysis.

prevents

Secure SDLC mandates type-safe design and review that can catch type-confusion flaws.

prevents

Application security requirements can specify strong typing and interface contracts that reduce type confusion.

prevents

Secure architecture principles promote type-safe languages and memory-safety mechanisms that mitigate type confusion.

prevents

Secure coding standards directly forbid unsafe type casts and require static-analysis checks for type confusion.
