Palo Alto Networks Expedition Missing Authentication Vulnerability
CVE-2024-5910 is a security vulnerability in Palo Alto Networks Expedition, added to CISA KEV on November 7, 2024. Patch priority: Patch this week.
What it is
Palo Alto Networks Expedition contains a missing authentication vulnerability that allows an attacker with network access to takeover an Expedition admin account and potentially access configuration secrets, credentials, and other data.
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 mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
