"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.");
