CPE [?]: cpe:/a:vmware:fusion

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.

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the VMware Fusion 8.1.x < 8.1.1 Shared Folders (HGFS) Guest DLL Hijacking Arbitrary Code Execution (VMSA-2016-0010) vulnerability:

Metasploit: exploit/windows/misc/vmhgfs_webdav_dll_sideload
[DLL Side Loading Vulnerability in VMware Host Guest Client Redirector]
Exploit-DB: exploits/windows/local/41711.rb
[EDB-41711: VMware Host Guest Client Redirector - DLL Side Loading (Metasploit)]

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.

WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.
