CVE-2025-0108: Palo Alto PAN-OS Auth Bypass Vulnerability

CVE-2025-0108 Overview

An authentication bypass in the Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to bypass the authentication otherwise required by the PAN-OS management web interface and invoke certain PHP scripts. While invoking these PHP scripts does not enable remote code execution, it can negatively impact the integrity and confidentiality of PAN-OS.

Critical Impact
This vulnerability can compromise the integrity and confidentiality of the network security infrastructure.

Technical Details for CVE-2025-0108

Vulnerability Analysis

This vulnerability exists due to the improper implementation of authentication controls within the management web interface of PAN-OS. An attacker with network access can exploit this flaw to bypass the authentication and invoke specific PHP scripts that should otherwise be protected.

Root Cause

The root cause of this vulnerability is the lack of stringent authentication controls in certain areas of the PAN-OS management web interface.

Attack Vector

This vulnerability is exploitable over the network by unauthenticated attackers with access to the management web interface.

php

// Example exploitation code (sanitized)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://target-ip/login.cgi");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "user=admin&password=123456");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

Detection Methods for CVE-2025-0108

Indicators of Compromise

Unusual login attempts to the management interface
Access to unauthorized PHP scripts
Network traffic from unexpected IP addresses

Detection Strategies

SentinelOne endpoint protection can monitor for unusual access patterns to the management interface and flag any attempt at authentication bypass. The system can also analyze logs for anomalies in access requests.

Monitoring Recommendations

Implement continuous monitoring of access logs for unauthorized access attempts and configure alerts for any access to protected scripts without proper authentication.

How to Mitigate CVE-2025-0108

Immediate Actions Required

Restrict access to the management web interface.
Monitor logs for unauthorized access attempts.
Update PAN-OS to the latest patched version.

Patch Information

Palo Alto Networks has released patches for affected versions of PAN-OS. Refer to the vendor advisory for detailed patch instructions.

Workarounds

Restrict web interface access to trusted IP addresses per Palo Alto best practices.

bash

# Configuration example
iptables -A INPUT -p tcp --dport 443 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
