CVE-2022-42046Public exploit

SYSTEM escalation via unchecked EPROCESS flag operations

Published Dec 20, 2022 · Updated Apr 17, 2025

Local privilege escalation in WFS Heaven Burns Red 2.5.0 and earlier allows local users to execute malicious programs as SYSTEM. The wfshbr64.sys and wfshbr32.sys drivers treat crafted IOCTL fields as an EPROCESS offset and bit mask, then apply unchecked bitwise operations to the caller's protection and signature flags. A low-privileged local account with access to an installed driver can manipulate kernel process metadata and run code with SYSTEM privileges.
