CVE-2025-0137 PAN-OS: Improper Neutralization of Input in the Management Web Interface

Description

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.

Product Status

Required Configuration for Exposure

The risk is greatest if you allow access to the management web interface from the internet or from any untrusted network either:

1. Directly; or

2. 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 web interface.

Use the following steps to identify your recently detected devices in our internet scans.

1. To find any assets that require remediation, visit the Assets section of the Customer Support Portal:https://support.paloaltonetworks.com and then select Products → Assets → All Assets → Remediation Required).

2. Review the list of your assets that we discovered in our scans to have an internet-facing management interface. We tagged these assets with ‘PAN-SA-2024-0015’ and a last seen timestamp (in UTC). If you do not see any such assets listed, then our scan did not find any devices associated with your account in the past three days that have an internet-facing management interface.
   

Severity:LOW, Suggested Urgency:MODERATE

The risk is highest when you allow access to the management interface from external IP addresses on the internet.
LOW– CVSS-BT: 1.1 /CVSS-B: 4.8 (CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/S:N/AU:N/R:U/V:C/RE:M/U:Amber)

You can greatly reduce the risk of exploitation by restricting web interface access to a jump box as the only system or source with access to the management interface. This ensures that attacks succeed only if they obtain privileged access through the IP addresses that you specify.
LOW– CVSS-BT: 0.3 /CVSS-B: 2.0 (CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/S:N/AU:N/R:U/V:C/RE:M/U:Amber)

Exploitation Status

CAPEC-195 Principal Spoof

Solution

Workarounds and Mitigations

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.
