CVE-2025-0133 Scanner

The scanner is utilized predominantly in enterprise environments that employ Palo Alto Networks PAN-OS for network security. It is used by IT administrators and security teams to safeguard network infrastructure against unauthorized access and threats. PAN-OS is integral to firewall configurations, Intrusion Prevention Systems (IPS), and securing VPN connections. The software allows administrators to manage enterprise-level security policies and network configurations remotely. Companies across all industries, especially those handling sensitive data, employ PAN-OS to maintain a secure and efficient network environment. The software is a critical part of maintaining compliance with cybersecurity standards and regulations.

The Cross-Site Scripting (XSS) vulnerability allows attackers to execute malicious scripts in the context of an authenticated user's browser. This occurs when a user clicks on a specially crafted link, potentially leading to phishing attacks. The vulnerability is of particular concern when utilizing the Clientless VPN feature, where clicking a malicious link could result in credential theft. It exploits the lack of input validation on certain end points, leading to the execution of arbitrary code. Users are exposed to risks through phishing, credential theft, and unauthorized data manipulation.

Technically, the vulnerability exploits the lack of input validation in the URL query parameters processed by the PAN-OS software. Specifically, an endpoint involved in the GlobalProtect gateway and portal features is susceptible. The vulnerable parameters include the user and portal fields in HTTP requests sent to SSL VPN configuration pages. Attackers can inject a payload containing the script tag to execute JavaScript in the victim's browser. This attack vector is significant in environments with a poorly configured portal user management system. Professionals must address these vulnerable endpoints to prevent exploitation.

Exploitation of this vulnerability can result in significant security breaches. Phishing attacks are likely to increase, leading to potential credential theft as users unwittingly submit their information to maliciously crafted portals. Confidential customer or company data may be at risk, potentially causing data breaches. Moreover, the network security could be compromised, allowing further infiltration into internal systems. Unauthorized access to sensitive resources is possible, damaging organizational integrity. Since the vulnerability affects core components of network management, its exploitation may lead to service disruptions and possible financial loss.
