👾 Exploit Exists🟡 Public PoC🦅 CISA Reported

Summary

The VBoxDrvNtDeviceControl function in VBoxDrv.sys in Sun xVM VirtualBox before 1.6.4 uses the METHOD_NEITHER communication method for IOCTLs and does not properly validate a buffer associated with the Irp object, which allows local users to gain privileges by opening the \.\VBoxDrv device and calling DeviceIoControl to send a crafted kernel address.

CISA provides regional cyber and physical services to support security and resilience across the United States. CISA monitor the most dangerious vulnerabilities and have identifed as being exploited but is not known by the CISA to be used in ransomware campaigns. This is subject to change at pace

The CISA's recommendation is: Apply updates per vendor instructions.
