CISA recently warned that attackers are exploiting a critical missing authentication vulnerability in Palo Alto Networks Expedition, a migration tool that can help convert firewall configuration from Checkpoint, Cisco, and other vendors to PAN-OS.
This security flaw, tracked as CVE-2024-5910, was patched in July, and threat actors can remotely exploit it to reset application admin credentials on Internet-exposed Expedition servers.
“Palo Alto 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,” CISA says.

Horizon3.ai vulnerability researcher Zach Hanley released a proof-of-concept exploit in October that can help chain this admin reset flaw with a CVE-2024-9464 command injection vulnerability (patched last month) to gain “unauthenticated” arbitrary command execution on vulnerable Expedition servers.
Admins who can’t immediately install security updates to block incoming attacks are advised to restrict Expedition network access to authorized users, hosts, or networks.
“All Expedition usernames, passwords, and API keys should be rotated after upgrading to the fixed version of Expedition. All firewall usernames, passwords, and API keys processed by Expedition should be rotated after updating,” the company cautions.
Palo Alto Networks has yet to update its security advisory to warn customers of ongoing CVE-2024-5910 attacks.
CISA also added the vulnerability to its Known Exploited Vulnerabilities Catalog on Thursday. As required by the binding operational directive (BOD 22-01) issued in November 2021, U.S. federal agencies must now secure vulnerable Palo Alto Networks Expedition servers on their networks against attacks within three weeks, by November 28.
“These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise,” the cybersecurity agency warned.
