What is CVE-2008-3431?

The VBoxDrvNtDeviceControl function in VBoxDrv.sys of Sun xVM VirtualBox versions prior to 1.6.4 can be exploited by local users. By invoking the DeviceIoControl function with a specially crafted kernel address, attackers can potentially gain elevated privileges. This occurs due to inadequate buffer validation associated with the Irp object, especially when using the METHOD_NEITHER communication method for IOCTLs. Proper mitigation involves updating to the latest version of VirtualBox to protect against this vulnerability.

CISA has reported CVE-2008-3431

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 CVE-2008-3431 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.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
