Description
CVE-2023-32046 is a high-severity elevation of privilege vulnerability affecting Microsoft Windows 10 Version 1809, specifically related to the MSHTML platform. The flaw allows an attacker with local access and limited privileges to escalate their rights to higher privileges on the affected system. Exploitation requires user interaction but no prior authentication, and the vulnerability impacts confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the vulnerability poses a significant risk if leveraged by attackers. The affected version is Windows 10 1809 (build 10.0.17763.0), which remains in use in some environments. European organizations using this legacy OS version are at risk, especially those with critical infrastructure or sensitive data. Mitigation involves applying security updates from Microsoft or upgrading to a supported Windows version.
