VMware Horizon View Agent 7.x < 7.5.4 / 7.10.1 / 7.11.0 Privilege Escalation (VMSA-2019-0023)

high Nessus Plugin ID 132753

Language:

Synopsis

The remote host has a virtual desktop agent installed that is affected by a privilege escalation vulnerability.

Description

The VMware Horizon View Agent installed on the remote host is 7.x prior to 7.5.4, 7.10.1, or 7.11.0. It is, therefore, affected by a DLL hijacking vulnerability due to insecure loading of a DLL by Cortado Thinprint. An authenticated, local attacker with normal user privileges can exploit this to escalate their privileges to administrator on a Windows machine where View Agent is installed.

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 Agent 7.5.4, 7.10.1, 7.11.0 or later.
