Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-23405 is a remote code execution vulnerability in the Remote Procedure Call Runtime component. It carries a CVSS 3.1 base score of 8.1 with the vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H and is associated with CWE-190. The flaw was published on 14 March 2023 and affects Microsoft Windows systems that expose RPC functionality.
An unauthenticated remote attacker can trigger the issue over the network without user interaction, although successful exploitation requires high attack complexity. If successful, the attacker can execute arbitrary code with the privileges of the RPC service, resulting in full compromise of confidentiality, integrity, and availability on the target system.
Microsoft’s Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-23405 provides official guidance and links to security updates that address the vulnerability. The current and peak EPSS scores both stand at 0.0507, indicating limited observed exploitation interest since disclosure.

Security testing in development can detect integer overflows before release.
Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.
Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.
Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.
Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
