Detailsinfo

A vulnerability was found in VMware ESX and ESXi up to 4.1/5.1 (Virtualization Software) and classified as critical. This issue affects some unknown functionality of the file lgtosync.sys of the component Windows 32-bit Guest OS Handler. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

lgtosync.sys in VMware Workstation 9.x before 9.0.3, VMware Player 5.x before 5.0.3, VMware Fusion 5.x before 5.0.4, VMware ESXi 4.0 through 5.1, and VMware ESX 4.0 and 4.1, when a 32-bit Windows guest OS is used, allows guest OS users to gain guest OS privileges via an application that performs a crafted memory allocation.

The weakness was presented 12/03/2013 as VMSA-2013-0014 as confirmed advisory (Website). It is possible to read the advisory at vmware.com. The public release was coordinated in cooperation with VMware. The identification of this vulnerability is CVE-2013-3519 since 05/08/2013. Attacking locally is a requirement. A simple authentication is required for exploitation. Technical details of the vulnerability are known, but there is no available exploit. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK. The advisory points out:

VMware ESX, Workstation and Fusion contain a vulnerability in the handling of control code in lgtosync.sys. A local malicious user may exploit this vulnerability to manipulate the memory allocation. This could result in a privilege escalation on 32-bit Guest Operating Systems running Windows 2000 Server, Windows XP or Windows 2003 Server on ESXi and ESX; or Windows XP on Workstation and Fusion. The vulnerability does not allow for privilege escalation from the Guest Operating System to the host. This means that host memory can not be manipulated from the Guest Operating System.

The vulnerability scanner Nessus provides a plugin with the ID 71214 (VMSA-2013-0014 : VMware Workstation, Fusion, ESXi and ESX patches address a guest privilege escalation), which helps to determine the existence of the flaw in a target environment. It is assigned to the family VMware ESX Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 216048 (VMWare ESXi 5.0.0 Patch Release ESXi500-201303001 Missing (KB2044373)).

Upgrading to version 4.1 or 5.1 eliminates this vulnerability. The upgrade is hosted for download at vmware.com. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (89416), Tenable (71214), SecurityFocus (BID 64075†), OSVDB (100514†) and Secunia (SA55684†). vmware.com is providing further details. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
