| 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 warns customers to restrict access to their next-generation firewalls because of a potential RCE flaw in the PAN-OS management interface.
Palo Alto Networks warns customers to limit access to their next-gen firewall management interface due to a potential remote code execution vulnerability in PAN-OS. The cybersecurity company has no further details on the vulnerability and said has yet to detect active exploitation.
“Palo Alto Networks is aware of a claim of a remote code execution vulnerability via the PAN-OS management interface. At this time, we do not know the specifics of the claimed vulnerability. We are actively monitoring for signs of any exploitation.” reads the advisory. “We strongly recommend customers to ensure access to your management interface is configured correctly in accordance with our recommended best practice deployment guidelines. In particular, we recommend that you ensure that access to the management interface is possible only from trusted internal IPs and not from the Internet. The vast majority of firewalls already follow this Palo Alto Networks and industry best practice.”
Palo Alto Networks recommends reviewing best practices for securing management access to its devices.
Guidelines to secure the Palo Alto management interface include isolating it on a dedicated management VLAN, using jump servers for access, limiting inbound IP addresses to approved management devices, and allowing only secure communication (SSH, HTTPS) and PING for connectivity testing.
The company currently believes Prisma Access and cloud NGFW are unaffected by this potential vulnerability.
The cybersecurity firm states that it does not have sufficient information about any indicators of compromise.
Cortex Xpanse and Cortex XSIAM customers using the ASM module can investigate internet-exposed instances by reviewing alerts from the Firewall Admin Login attack surface rule.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a Palo Alto Expedition Missing Authentication Vulnerability, tracked as CVE-2024-5910, to its Known Exploited Vulnerabilities (KEV) catalog.
In July, Palo Alto released security updates to address five security flaws impacting its products, the most severe issue, tracked as CVE-2024-5910 (CVSS score: 9.3), is a missing authentication for a critical function in Palo Alto Networks Expedition that can lead to an admin account takeover.
