Trellix Agent < 5.7.8 Privilege Escalation (SB10391)

medium Nessus Plugin ID 169456

Language:

Synopsis

A security management agent installed on the remote host is affected by a privilege escalation vulnerability.

Description

The version of Trellix Agent, formerly McAfee Agent or McAfee Policy Orchestrator (ePO) Agent, installed on the remote host is prior to 5.7.8. It is, therefore, affected by an privilege escalation vulnerability due to an uncontrolled search path. An attacker with admin access to the affected host can place a malicious DLL in the restricted Windows System folder to elevate their privileges to System.

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

Solution

Upgrade to McAfee Agent version 5.7.8 or later.
