Description

An untrusted search path vulnerability exists in the Palo Alto Networks Cortex XDR agent that enables a local attacker with file creation privilege in the Windows root directory (such as C:\) to store a program that can then be unintentionally executed by another local user when that user utilizes a Live Terminal session.

This issue impacts:

Cortex XDR agent 5.0 versions earlier than Cortex XDR agent 5.0.12 on Windows;

Cortex XDR agent 6.1 versions earlier than Cortex XDR agent 6.1.9 on Windows;

Cortex XDR agent 7.2 versions earlier than Cortex XDR agent 7.2.4 on Windows;

Cortex XDR agent 7.3 versions earlier than Cortex XDR agent 7.3.2 on Windows.
