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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly prevent type-confusion flaws via safe typing, static analysis, and code review while the control itself addresses many additional weaknesses.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development can detect type-confusion vulnerabilities through fuzzing and static analysis.
Secure SDLC mandates type-safe design and review that can catch type-confusion flaws.
Application security requirements can specify strong typing and interface contracts that reduce type confusion.
Secure architecture principles promote type-safe languages and memory-safety mechanisms that mitigate type confusion.
Secure coding standards directly forbid unsafe type casts and require static-analysis checks for type confusion.
