VMware Fusion 8.1.x < 8.1.1 Shared Folders (HGFS) Guest DLL Hijacking Arbitrary Code Execution (VMSA-2016-0010)

high Nessus Plugin ID 92943

Language:

Synopsis

A virtualization application installed on the remote Mac OS X host is affected by an arbitrary code execution vulnerability.

Description

The version of VMware Fusion installed on the remote Mac OS X host is 8.1.x prior to 8.1.1. It is, therefore, affected by an arbitrary code execution vulnerability in the Shared Folders (HGFS) feature due to improper loading of Dynamic-link library (DLL) files from insecure paths, including the current working directory, which may not be under user control. A remote attacker can exploit this vulnerability, by placing a malicious DLL in the path or by convincing a user into opening a file on a network share, to inject and execute arbitrary code in the context of the current user.

Solution

Upgrade to VMware Fusion 8.1.1 or later.

Note that VMware Tools on Windows-based guests that use the Shared Folders (HGFS) feature must also be updated to completely mitigate the vulnerability.
