Description

A reflected cross-site scripting (XSS) vulnerability in the GlobalProtect™ gateway and portal features of Palo Alto Networks PAN-OS® software enables execution of malicious JavaScript in the context of an authenticated Captive Portal user's browser when they click on a specially crafted link. The primary risk is phishing attacks that can lead to credential theft—particularly if you enabled Clientless VPN.

There is no availability impact to GlobalProtect features or GlobalProtect users. Attackers cannot use this vulnerability to tamper with or modify contents or configurations of the GlobalProtect portal or gateways. The integrity impact of this vulnerability is limited to enabling an attacker to create phishing and credential-stealing links that appear to be hosted on the GlobalProtect portal.

For GlobalProtect users with Clientless VPN enabled, there is a limited impact on confidentiality due to inherent risks of Clientless VPN that facilitate credential theft. You can read more about this risk in the informational bulletin PAN-SA-2025-0005. There is no impact to confidentiality for GlobalProtect users if you did not enable (or you disable) Clientless VPN.

Workarounds and Mitigations

Customers with a Threat Prevention subscription can block attacks for this vulnerability by enabling Threat ID 510003 and 510004 from Applications and Threats content version 8995.

For all Cloud NGFW, PAN-OS, and Prisma Access deployments, it is crucial to ensure that Vulnerability Protection profiles are explicitly applied to the security rules that process traffic from GlobalProtect interfaces. This ensures the Threat Prevention signatures are actively enforced. For detailed guidance on applying Vulnerability Protection to GlobalProtect interfaces, please refer to: https://live.paloaltonetworks.com/t5/globalprotect-articles/applying-vulnerability-protection-to-globalprotect-interfaces/ta-p/340184.

You can also disable Clientless VPN to reduce impact in the event of exploitation, though this will not block the exploit in it's entirety. For more information, review the security advisory PAN-SA-2025-0005.

Previous versions of this advisory have listed the recommended content version as 8970 and 8990. We now recommend 8995 as it has the latest updates to the signatures to cover additional exploit variants.
