Synopsis

A security management agent installed on the remote host is affected by a missing authorization vulnerability.

Description

The version of McAfee Agent, formerly McAfee ePolicy Orchestrator (ePO) Agent, installed on the remote host is 5.x prior to 5.7.3. It is, therefore, affected by the following vulnerabilities:

- An improper privilege management vulnerability exists due to a local user having the ability to edit the event log. An authenticated, attacker can exploit this, via by editing the agents event log prior to the events being sent to the ePO server. (CVE-2021-31839)
- An unsigned DLL preloading attack vulnerability exists. An authenticated, local attacker can exploit this and load malicious libraries of functionality on the remote host due to an insufficient validation of resources loaded by the application at runtime. (CVE-2021-31840) 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 McAfee Agent version 5.7.3 or later.
