CVE-2024-3387 Siemens CVE debrief

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.

Who should care

Organizations operating Siemens RUGGEDCOM APE1808 devices with Palo Alto Networks Virtual NGFW deployments, particularly those in industrial and critical infrastructure environments where Panorama central management is used for firewall administration. Security teams responsible for certificate lifecycle management and encrypted communications in OT/ICS networks should prioritize this fix.

Technical summary

CVE-2024-3387 stems from a weak (low bit strength) device certificate implementation in Palo Alto Networks Panorama software. The insufficient cryptographic strength allows an attacker with sufficient computing resources to perform a meddler-in-the-middle (MitM) attack, capturing and potentially decrypting encrypted traffic between the Panorama management server and managed firewalls. This exposure could lead to disclosure of sensitive management information. The vulnerability affects Siemens RUGGEDCOM APE1808 devices when configured with Palo Alto Networks Virtual NGFW. Remediation requires upgrading to Virtual NGFW V11.1.2-h3.

Defensive priority
