| CVE-2024-5910 | Unauthenticated Admin Account Takeover in Palo Alto Networks Expedition CVE-2024-5910 is a missing authentication flaw (CWE-306) in Palo Alto Networks Expedition, a tool used to migrate, tune, and enrich firewall configurations. An attacker with network access to an Expedition instance can exploit the unauthenticated critical function to take over the Expedition admin account without any credentials. Once in control, the attacker can access configuration secrets, credentials, and other data imported into Expedition, and public research (horizon3.ai) shows it can be chained with other Expedition bugs for full system compromise. Any organization running Expedition — particularly instances reachable from the internet or shared networks — is affected. The flaw is actively exploited: it was added to CISA's Known Exploited Vulnerabilities catalog on 2024-11-07, carries a 91.8% EPSS exploitation probability, and is being exploited alongside related Expedition and firewall bugs (CVE-2024-9463, CVE-2024-9465). Do: Apply the vendor's patched Expedition release per Palo Alto Networks' advisory; if the tool is no longer needed, decommission or discontinue it, as CISA permits. Until patched, restrict network access to Expedition to trusted management hosts and remove it from internet exposure. Check Expedition logs for signs of unauthorized admin access and rotate any credentials or secrets stored in the tool. | 9.3 | 92% | KEV PoC |

Palo Alto Networks has released security updates to address five security flaws impacting its products, including a critical bug that could lead to an authentication bypass.
Cataloged as CVE-2024-5910 (CVSS score: 9.3), the vulnerability has been described as a case of missing authentication in its Expedition migration tool that could lead to an admin account takeover.
"Missing authentication for a critical function in Palo Alto Networks Expedition can lead to an Expedition admin account takeover for attackers with network access to Expedition," the company said in an advisory. "Configuration secrets, credentials, and other data imported into Expedition is at risk due to this issue."
The flaw impacts all versions of Expedition prior to version 1.2.92, which remediates the problem. Synopsys Cybersecurity Research Center's (CyRC) Brian Hysell has been credited with discovering and reporting the issue.
While there is no evidence that the vulnerability has been exploited in the wild, users are advised to update to the latest version to secure against potential threats.
As workarounds, Palo Alto Networks is recommending that network access to Expedition is restricted to authorized users, hosts, or networks.
Also fixed by the American cybersecurity firm is a newly disclosed flaw in the RADIUS protocol called BlastRADIUS (CVE-2024-3596) that could allow a bad actor with capabilities to perform an adversary-in-the-middle (AitM) attack between Palo Alto Networks PAN-OS firewall and a RADIUS server to sidestep authentication.
The vulnerability then permits the attacker to "escalate privileges to 'superuser' when RADIUS authentication is in use and either CHAP or PAP is selected in the RADIUS server profile," it said.
The following products are affected by the shortcomings:
- PAN-OS 11.1 (versions < 11.1.3, fixed in >= 11.1.3)
- PAN-OS 11.0 (versions < 11.0.4-h4, fixed in >= 11.0.4-h4)
- PAN-OS 10.2 (versions < 10.2.10, fixed in >= 10.2.10)
- PAN-OS 10.1 (versions < 10.1.14, fixed in >= 10.1.14)
- PAN-OS 9.1 (versions < 9.1.19, fixed in >= 9.1.19)
- Prisma Access (all versions, fix expected to be released on July 30)
It also noted that neither CHAP nor PAP should be used unless they are encapsulated by an encrypted tunnel since the authentication protocols do not offer Transport Layer Security (TLS). They are not vulnerable in cases where they are used in conjunction with a TLS tunnel.
However, it's worth noting that PAN-OS firewalls configured to use EAP-TTLS with PAP as the authentication protocol for a RADIUS server are also not susceptible to the attack.
