Synopsis

A security management agent installed on the remote host is affected by multiple vulnerabilities.

Description

The version of McAfee Agent, formerly McAfee ePolicy Orchestrator (ePO) Agent, installed on the remote host is prior to 5.7.4. It is, therefore, affected by the following vulnerabilities:

- Improper access control vulnerability in the repair process for McAfee Agent for Windows prior to 5.7.4 could allow a local attacker to perform a DLL preloading attack using unsigned DLLs. This would result in elevation of privileges and the ability to execute arbitrary code as the system user, through not correctly protecting a temporary directory used in the repair process and not checking the DLL signature.
(CVE-2021-31847)

- A DLL sideloading vulnerability in McAfee Agent for Windows prior to 5.7.4 could allow a local user to perform a DLL sideloading attack with an unsigned DLL with a specific name and in a specific location.
This would result in the user gaining elevated permissions and the ability to execute arbitrary code as the system user, through not checking the DLL signature. (CVE-2021-31841)

- Improper privilege management vulnerability in maconfig for McAfee Agent for Windows prior to 5.7.4 allows a local user to gain access to sensitive information. The utility was able to be run from any location on the file system and by a low privileged user. (CVE-2021-31836)

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 5.7.4 or later.
