Cortex XDR Agent: Improper Privilege Management
CVE-2024-5907 is a high-severity improper privilege management vulnerability in Cortex XDR Agent from Palo Alto Networks, with a CVSS 3.1 base score of 7.0 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 7.9.102-CE, 8.2.3, 8.3.1 as the first without the flaw, so updating Cortex XDR Agent to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.13% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Cortex XDR Agent to 7.9.102-CE or 8.2.3 or 8.3.1, whichever matches your release line, or a later version.
- Read the advisory on security.paloaltonetworks.com for workarounds and exact fixed builds.

Official description
A privilege escalation (PE) vulnerability in the Palo Alto Networks Cortex XDR agent on Windows devices enables a local user to execute programs with elevated privileges. However, execution does require the local user to successfully exploit a race condition, which makes this vulnerability difficult to exploit.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
