CVE-2024-3387: Palo Alto Networks PAN-OS

Medium severity, CVSS 5.9. EPSS: 0.2% chance of exploitation in the next 30 days.

A weak (low bit strength) device certificate in Palo Alto Networks Panorama software enables an attacker to perform a meddler-in-the-middle (MitM) attack to capture encrypted traffic between the Panorama management server and the firewalls it manages. With sufficient computing resources, the attacker could break encrypted communication and expose sensitive information that is shared between the management server and the firewalls.

Affected products
