Description
An authentication bypass in Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to gain PAN-OS administrator privileges to perform administrative actions, tamper with the configuration, or exploit other authenticated privilege escalation vulnerabilities like CVE-2024-9474 https://security.paloaltonetworks.com/CVE-2024-9474 . The risk of this issue is greatly reduced if you secure access to the management web interface by restricting access to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 . This issue is applicable only to PAN-OS 10.2, PAN-OS 11.0, PAN-OS 11.1, and PAN-OS 11.2 software. Cloud NGFW and Prisma Access are not impacted by this vulnerability.
Comprehensive Technical Analysis of CVE-2024-0012
1. Vulnerability Assessment and Severity Evaluation
CVE ID: CVE-2024-0012
Description: The vulnerability involves an authentication bypass in Palo Alto Networks PAN-OS software, allowing an unauthenticated attacker with network access to the management web interface to gain PAN-OS administrator privileges. This can lead to unauthorized administrative actions, configuration tampering, and exploitation of other authenticated privilege escalation vulnerabilities such as CVE-2024-9474.
CVSS Score: 9.8
Severity Evaluation:
- Critical: The CVSS score of 9.8 indicates a critical vulnerability. The high score is due to the potential for complete administrative control over the affected systems, leading to significant security risks.
- Impact: The vulnerability can result in unauthorized access, data breaches, and potential disruption of network services.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Network Access: An attacker needs network access to the management web interface of the PAN-OS software.
- Unauthenticated Access: The attacker does not require any credentials to exploit the vulnerability.
Exploitation Methods:
- Authentication Bypass: The attacker can bypass the authentication mechanism to gain administrative privileges.
- Configuration Tampering: Once authenticated, the attacker can modify configurations, disable security features, or create backdoors.
- Privilege Escalation: The attacker can exploit other vulnerabilities like CVE-2024-9474 to escalate privileges further.
3. Affected Systems and Software Versions
Affected Software Versions:
- PAN-OS 10.2
- PAN-OS 11.0
- PAN-OS 11.1
- PAN-OS 11.2
Unaffected Systems:
