The McAfee VirusScan Console (mcconsol.exe) in McAfee Active Response (MAR) before 1.1.0.161, Agent (MA) 5.x before 5.0.2 Hotfix 1110392 (5.0.2.333), Data Exchange Layer 2.x (DXL) before 2.0.1.140.1, Data Loss Prevention Endpoint (DLPe) 9.3 before Patch 6 and 9.4 before Patch 1 HF3, Device Control (MDC) 9.3 before Patch 6 and 9.4 before Patch 1 HF3, Endpoint Security (ENS) 10.x before 10.1, Host Intrusion Prevention Service (IPS) 8.0 before 8.0.0.3624, and VirusScan Enterprise (VSE) 8.8 before P7 (8.8.0.1528) on Windows allows local administrators to bypass intended self-protection rules and disable the antivirus engine by modifying registry keys.

XML Entity Expansion injection vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 September 2021 Update allows a local user to initiate high CPU and memory consumption resulting in a Denial of Service attack through carefully editing the EPDeploy.xml file and then executing the setup process.

Null Pointer Dereference vulnerability in McAfee Endpoint Security (ENS)

A Null Pointer Dereference vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2021 Update allows a local administrator to cause Windows to crash via a specific system call which is not handled correctly. This varies by machine and had partial protection prior to this update.

Improper Access Control in the ENS installer

Improper Access Control vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2021 Update allows local administrators to prevent the installation of some ENS files by placing carefully crafted files where ENS will be installed. This is only applicable to clean installations of ENS as the Access Control rules will prevent modification prior to up an upgrade.

Stored Cross Site Scripting in ENS

A stored cross site scripting vulnerability in ePO extension of McAfee Endpoint Security (ENS) prior to 10.7.0 February 2021 Update allows an ENS ePO administrator to add a script to a policy event which will trigger the script to be run through a browser block page when a local non-administrator user triggers the policy.

Improper Access Control in the ENS installer

Improper Access Control in attribute in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2021 Update allows authenticated local administrator user to perform an uninstallation of the anti-malware engine via the running of a specific command with the correct parameters.

Clear text storage of sensitive Information in ENS

Clear text storage of sensitive Information in memory vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2021 Update allows a local user to view ENS settings and credentials via accessing process memory after the ENS administrator has performed specific actions. To exploit this, the local user has to access the relevant memory location immediately after an ENS administrator has made a configuration change through the console on their machine

Cross-site Scripting (XSS) in firewall ePO extension of McAfee Endpoint Security (ENS)

Cross site scripting vulnerability in the firewall ePO extension of McAfee Endpoint Security (ENS) prior to 10.7.0 November 2020 Update allows administrators to inject arbitrary web script or HTML via the configuration wizard.

Cross-Site Request Forgery (CSRF) in firewall ePO extension of McAfee Endpoint Security (ENS)

Cross Site Request Forgery vulnerability in the firewall ePO extension of McAfee Endpoint Security (ENS) prior to 10.7.0 November 2020 Update allows an attacker to execute arbitrary HTML code due to incorrect security configuration.

Unquoted service executable path in McAfee Endpoint Security (ENS)

Unquoted service executable path in McAfee Endpoint Security (ENS) prior to 10.7.0 November 2020 Update allows local users to cause a denial of service and malicious file execution via carefully crafted and named executable files.

Authentication Protection Bypass vulnerability in ENS for Windows

Authentication Protection Bypass vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 September 2020 Update allows physical local users to bypass the Windows lock screen via triggering certain detection events while the computer screen is locked and the McTray.exe is running with elevated privileges. This issue is timing dependent and requires physical access to the machine.

Exposure of Sensitive Information in ENS for Windows

Information Disclosure Vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 September 2020 Update allows local users to gain access to sensitive information via incorrectly logging of sensitive information in debug logs.

Protection Mechanism Failure in ENS for Windows

Protection Mechanism Failure vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 September 2020 Update allows local administrator to temporarily reduce the detection capability allowing otherwise detected malware to run via stopping certain Microsoft services.

Improper Access Control Vulnerability in ENS for Windows

Improper Access Control vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 September 2020 Update allows local users to access files which the user otherwise would not have access to via manipulating symbolic links to redirect McAfee file operations to an unintended file.

Transmission of data in clear text by McAfee ENS

Cleartext Transmission of Sensitive Information between McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2021 Update and McAfee Global Threat Intelligence (GTI) servers using DNS allows a remote attacker to view the requests from ENS and responses from GTI over DNS. By gaining control of an intermediate DNS server or altering the network DNS configuration, it is possible for an attacker to intercept requests and send their own responses.

McAfee firewall rules not enforced correctly

Exploiting incorrectly configured access control security levels vulnerability in ENS Firewall in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 April 2020 and 10.6.1 April 2020 updates allows remote attackers and local users to allow or block unauthorized traffic via pre-existing rules not being handled correctly when updating to the February 2020 updates.

McAfee processes not protected

Protection mechanism failure in all processes in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 April 2020 Update allows local users to stop certain McAfee ENS processes, reducing the protection offered.
