Useful 0 Not Useful 0

Executive Summary

The vulnerability in Idira Endpoint Privilege Manager Agent versions prior to 26.5 involves improper access control within high-privileged agent components.

A local attacker with low privileges could exploit this flaw by manipulating internal communication mechanisms or file operations.

Under certain conditions, this exploitation could allow the attacker to bypass permission restrictions and perform unauthorized local actions with elevated privileges.

Mitigation Strategies

To mitigate this vulnerability, upgrade the Idira Endpoint Privilege Manager Agent to version 26.5 or later, as this version includes security and performance improvements that address improper access control issues.

Ensure that you are using the Palo Alto Networks-signed PKG installation method on macOS for secure installation, as the unsigned custom PKG method is deprecated and planned for removal.

Review and apply the latest security enhancements and configuration best practices provided in the release notes for your platform (macOS, Linux, or Windows) to reduce the risk of exploitation.

Detection Guidance

This vulnerability affects Idira Endpoint Privilege Manager Agent versions prior to 26.5. To detect if your system is vulnerable, you should first verify the installed version of the CyberArk Endpoint Privilege Manager (EPM) agent on your endpoints.

For Windows systems, you can check the installed EPM agent version by running the following command in PowerShell or Command Prompt:

• wmic product where "name like '%Endpoint Privilege Manager%'" get name, version

For Linux systems, you can check the installed package version using commands such as:

• rpm -qa | grep endpoint_privilege_manager
• or
• dpkg -l | grep endpoint_privilege_manager

For macOS systems, you can check the installed EPM agent version by running:

• pkgutil --pkg-info com.cyberark.endpointprivilegemanager

If the version is prior to 26.5, your system is potentially vulnerable to this privilege escalation issue. Additionally, monitoring for unusual local privilege escalations or unauthorized access attempts related to internal communication mechanisms or file operations of the EPM agent could help detect exploitation attempts.
