A vulnerability identified in the HX Agent driver file fekern.sys allowed a threat actor with local user access the ability to gain elevated system privileges. Utilization of a Bring Your Own Vulnerable Driver (BYOVD) was leveraged to gain access to the critical Windows process memory lsass.exe (Local Security Authority Subsystem Service). The fekern.sys is a driver file associated with the HX Agent (used in all existing HX Agent versions). The vulnerable driver installed in a product or a system running a fully functional HX Agent is, itself, not exploitable as the product’s tamper protection restricts the ability to communicate with the driver to only the Agent’s processes.

An improper access restriction to a folder in Bitdefender Endpoint Security Tools for Mac (BEST) before 7.20.52.200087 allows local users with administrative privileges to bypass the configured uninstall password protection. An unauthorized user with sudo privileges can manually remove the application directory (/Applications/Endpoint Security for Mac.app/) and the related directories within /Library/Bitdefender/AVP without needing the uninstall password.

Exposure of sensitive information to local unauthorized actors in Elastic Agent and Elastic Security Endpoint can lead to loss of confidentiality and impersonation of Endpoint to the Elastic Stack. This issue was identified by Elastic engineers and Elastic has no indication that it is known or has been exploited by malicious actors.

Denial of service vulnerability present shortly after product installation or upgrade, potentially allowed an attacker to render ESET’s security product inoperable, provided non-default preconditions were met.

Unquoted service path in ESET products allows to drop a prepared program to a specific location and run on boot with the NT AUTHORITY\NetworkService permissions.

Improper cleanup vulnerability in exceptions thrown in FireEye Endpoint Security, affecting version 5.2.0.958244. This vulnerability could allow an attacker to send multiple request packets to the containment_notify/preview parameter, which could lead to a service outage.
