Vulnerability identifier: #VU4865

CSH Severity: Medium

CVSS v4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2014-4113

CWE-ID: CWE-119

Exploitation vector: Local access

Exploit availability: The vulnerability is being exploited in the wild

The vulnerability allows a local attacker to obtain elevated privileges on the target system.

The weakness exists due to improper handling of objects in memory by kernel-mode driver (win32k.sys). A local attacker can run a specially crafted application to gain elevated privileges and take complete control of the system.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.
