Palo Alto Networks PAN-OS Remote Code Execution Vulnerability
What it is
Remote Code Execution in PAN-OS with GlobalProtect Portal or GlobalProtect Gateway Interface enabled.
Known to be used in ransomware campaigns.Active threat actors have chained this vulnerability into ransomware operations — treat patching as a same-week priority, not a "next maintenance window" task. The coping action is the same one below; the urgency is higher.
Who's affected
Affects anyone behind a Palo Alto firewall or using GlobalProtect VPN. The firewall is the network edge; the VPN is how remote workers reach inside the perimeter — exploitation puts an attacker on the internal network without touching a workstation.
What to do
Apply updates per vendor instructions.
CISA action deadline: July 10, 2022. Federal agencies must complete the required action by this date. For private SMBs the deadline is advisory — but treat it as a strong recommendation, especially if you handle regulated data (HIPAA, GLBA, ABA model rules).
