Researchers from Chinese cybersecurity firm Qihoo 360 have made public technical details that can be used to construct a proof-of-concept (PoC) exploit for CVE-2019-0808, a recently patched Windows vulnerability that has been involved in targeted attacks.
The existence of CVE-2019-0808 was brought to light a week ago when Google’s Threat Analysis Group revealed that it had been exploited alongside CVE-2019-5786, a Chrome vulnerability that the browser’s developers patched on March 1.
Google released limited technical information about the Windows vulnerability before Microsoft managed to release a patch. A fix was made available to users on March 12, when Microsoft released its Patch Tuesday updates.
The security hole affects the Win32k component in Windows and allows an authenticated attacker to elevate privileges and execute arbitrary code in kernel mode. It can also be used to escape sandboxes if combined with a web browser vulnerability.
The flaw only appears to affect Windows 7 and Windows Server 2008 as Windows 10 includes some additional mitigations that prevent exploitation.
