CVE-2023-51776

Local privilege escalation and arbitrary code execution

Published Jul 2, 2024 · Updated Mar 13, 2025

Improper privilege management in Jungo WinDriver before 12.1.0 allows local users to gain Windows system privileges. Public advisories do not identify the affected driver interface, privileged operation, or input handling responsible for the flaw. Successful exploitation requires low-privileged local access and execution of malicious code on a Windows computer with an affected driver, granting arbitrary command execution with system privileges.
