Detailsinfo

A vulnerability classified as critical has been found in VMware Workstation, Fusion, ESX and View up to 9.0.1 (Virtualization Software). Affected is some unknown functionality of the file VMCI.SYS. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Virtual Machine Communication Interface (VMCI) implementation in vmci.sys in VMware Workstation 8.x before 8.0.5 and 9.x before 9.0.1 on Windows, VMware Fusion 4.1 before 4.1.4 and 5.0 before 5.0.2, VMware View 4.x before 4.6.2 and 5.x before 5.1.2 on Windows, VMware ESXi 4.0 through 5.1, and VMware ESX 4.0 and 4.1 does not properly restrict memory allocation by control code, which allows local users to gain privileges via unspecified vectors.

The weakness was disclosed 02/07/2013 by Derek Soeder and Kostya Kortchinsky with Cylance Inc./Microsoft as VMSA-2013-0002 as confirmed advisory (Website). The advisory is shared for download at vmware.com. This vulnerability is traded as CVE-2013-1406 since 01/19/2013. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known.

A public exploit has been developed by Artem Shishkin and been published 4 weeks after the advisory. The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. As 0-day the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 64643 (VMSA-2013-0002 : VMware ESX, Workstation, Fusion, and View VMCI privilege escalation vulnerability), 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 216043 (VMWare ESXi 4.0.0 Patch Release ESXi400-201302001 Missing (KB2041344)).

Upgrading to version 9.0.1 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (81947), Exploit-DB (40164), Tenable (64643), SecurityFocus (BID 57867†) and OSVDB (90019†). Further details are available at nakedsecurity.sophos.com. The entries VDB-7573, VDB-7572, VDB-7575 and VDB-7574 are pretty similar.
