What to do

AI-suggested

1. Immediate mitigation should focus on restricting access to the PA-7500 devices and their stored keys, ensuring only trusted administrators have high-level privileges. 2. Disable MACsec on NGFW clusters if it is not strictly required, to eliminate exposure of the CAK. 3. Monitor and audit access logs for any unusual administrative activity or attempts to access key storage areas on the devices. 4. Implement network segmentation and strict access controls around firewall management interfaces to reduce the risk of key compromise. 5. Upon availability, promptly apply vendor patches or firmware updates addressing this vulnerability. 6. Consider deploying additional encryption or key management solutions external to the firewall cluster to protect sensitive keys. 7. Conduct regular security assessments and penetration tests focusing on key management and inter-device communication security within NGFW clusters. 8. Educate network and security teams about the risks of cleartext key storage and best practices for secure key handling in clustered environments.

Description

A problem with the implementation of the MACsec protocol in Palo Alto Networks PAN-OS® results in the cleartext exposure of the connectivity association key (CAK). This issue is only applicable to PA-7500 Series devices which are in an NGFW cluster. A user who possesses this key can read messages being sent between devices in a NGFW Cluster. There is no impact in non-clustered firewalls or clusters of firewalls that do not enable MACsec.
