CVE-2024-3387Network attack vector

Sensitive information disclosure via weak device certificate

Published Apr 10, 2024 · Updated Aug 1, 2024

Inadequate encryption strength in PAN-OS Panorama allows man-in-the-middle attackers to expose sensitive management traffic. The Panorama-to-firewall channel relies on a device certificate with insufficient bit strength, so captured ciphertext can be decrypted with sufficient computing resources. The attacker must occupy the network path between Panorama and a managed firewall; the reported consequence is limited to confidential data exposure.
