McAfee Agent < 5.7.5 Multiple Vulnerabilities (SB10378)

high Nessus Plugin ID 157126

Language:

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 5.7.5. It is, therefore, affected by the following vulnerabilities:

- A command Injection Vulnerability in McAfee Agent (MA) for Windows prior to 5.7.5 allows local users to inject arbitrary shell code into the file cleanup.exe. The malicious clean.exe file is placed into the relevant folder and executed by running the McAfee Agent deployment feature located in the System Tree.
An attacker may exploit the vulnerability to obtain a reverse shell which can lead to privilege escalation to obtain root privileges. (CVE-2021-31854)

- A privilege escalation vulnerability in the McAfee Agent prior to 5.7.5. McAfee Agent uses openssl.cnf during the build process to specify the OPENSSLDIR variable as a subdirectory within the installation directory. A low privilege user could have created subdirectories and executed arbitrary code with SYSTEM privileges by creating the appropriate pathway to the specifically created malicious openssl.cnf file. (CVE-2022-0166) 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 5.7.5 or later.
