The risk is greatest if you enabled access to the management interface from the internet or from any untrusted network either:
Directly; or
Through a dataplane interface that includes a management interface profile.
You greatly reduce the risk if you ensure that you allow only trusted internal IP addresses to access the management interface.
Use the following steps to identify your recently detected devices in our internet scans.
To find any assets that require remediation action, visit the Assets section of the Customer Support Portal a https://support.paloaltonetworks.com (Products → Assets → All Assets → Remediation Required).
Review the list of your devices that we discovered in our scans to have an internet-facing management interface. We tagged these devices with ‘PAN-SA-2024-0015’ and a last seen timestamp (in UTC). If you do not see any such devices listed, then our scan did not find any devices associated with your account that had an internet-facing management interface within the past three days.
GlobalProtect™ portals and gateways are not vulnerable to this issue. However, if you configure a management profile on interfaces with GlobalProtect portals or gateways, then you expose the device to attacks through the management web interface (typically accessible on port 4443).
An improper input neutralization vulnerability in the management web interface of the Palo Alto Networks PAN-OS® software enables a malicious authenticated read-write administrator to impersonate another legitimate authenticated PAN-OS administrator.
The attacker must have network access to the management web interface to exploit this issue. You greatly reduce the risk of this issue by restricting access to the management web interface to only trusted internal IP addresses according to our recommended critical deployment guidelines.
This issue does not affect Cloud NGFW and all Prisma® Access instances.

| All other older unsupported PAN-OS versions | Upgrade to a supported fixed version. |
Recommended mitigation—The vast majority of firewalls already follow Palo Alto Networks and industry best practices. However, if you have not already, we strongly recommend that you secure access to your management interface according to our critical deployment guidelines. Specifically, you should restrict management interface access to only trusted internal IP addresses.
