VMware Horizon View Client < 5.5.0 Information Disclosure (VMSA-2020-0024)

medium Nessus Plugin ID 143450

Language:

Synopsis

A virtualization application installed on the remote host is affected by an information disclosure vulnerability.

Description

The version of VMware Horizon Client for Windows installed on the remote host is less than 5.5.0. It is, therefore, affected by an information disclosure vulnerability due to incorrect validation of user input. A malicious attacker with local privileges on the machine where Horizon Client for Windows is installed may be able to retrieve hashed credentials if the client crashes.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to VMWare Horizon View Client 5.5.0 or later
