CVE-2024-5910: 
Palo Alto Expedition vulnerability analysis and mitigation

CVE-2024-5910 is a critical vulnerability (CVSS score: 9.3) discovered in Palo Alto Networks Expedition, a tool designed for configuration migration and tuning. The vulnerability, identified by Brian Hysell from Synopsys CyRC, involves missing authentication for a critical function that can lead to admin account takeover. The issue affects Expedition versions prior to 1.2.92 and was initially disclosed on July 10, 2024 (Palo Advisory, Hacker News).

The vulnerability stems from an unauthenticated access to a critical PHP file located in /var/www/html/ directory that allows resetting the admin password. The flaw is characterized by CWE-306 (Missing Authentication for Critical Function) and received a CVSS v4.0 base score of 9.3 CRITICAL. The attack vector is network-based with low attack complexity, requiring no privileges or user interaction (Palo Advisory, Horizon3).

The vulnerability allows attackers with network access to Expedition to take over admin accounts and potentially access sensitive data. Since Expedition is used for configuration migration, all configuration secrets, credentials, and other data imported into the system are at risk. The impact affects confidentiality, integrity, and availability at high levels (Palo Advisory).

The vulnerability has been patched in Expedition version 1.2.92 and later versions. As a workaround, organizations are advised to restrict network access to Expedition to only authorized users, hosts, or networks. It's recommended to ensure the application is not exposed to the internet unless absolutely necessary (Palo Advisory).
