On November 19, 2024, Palo Alto Networks disclosed two critical vulnerabilities in its PAN-OS software, CVE-2024-0012 an Authentication Bypas, and CVE-2024-9474 a Privilege Escalation. These vulnerabilities enable attackers to gain unauthorized administrative access and escalate privileges to root level. Exploitation of these vulnerabilities, observed in the wild, has been attributed to a targeted campaign dubbed Operation Lunar Peek.

Affected Products

CVE-2024-0012 (Authentication Bypass)

• PAN-OS 10.2: Versions prior to 10.2.12-h2
• PAN-OS 11.0: Versions prior to 11.0.6-h1
• PAN-OS 11.1: Versions prior to 11.1.5-h1
• PAN-OS 11.2: Versions prior to 11.2.4-h1

CVE-2024-9474 (Privilege Escalation)

• PAN-OS 10.1: Versions prior to 10.1.14-h6
• PAN-OS 10.2, 11.0, 11.1, 11.2: Same affected versions as CVE-2024-0012

Technical Details

CVE-2024-0012 – Authentication Bypass

• Severity: Critical (CVSS 9.3)
• Description: Exploitation allows unauthenticated attackers to bypass authentication by supplying a crafted HTTP header (x-pan-authcheck: off) to the PAN-OS management web interface. This grants administrative privileges, enabling configuration tampering and potential exploitation of CVE-2024-9474.

CVE-2024-9474 – Privilege Escalation

• Severity: Medium (CVSS 6.9)
• Description: This flaw enables authenticated administrators to escalate privileges to root, allowing actions such as disabling security features and compromising system integrity.

Exploitation

Operation Lunar Peek

• Exploitation has been observed on devices with exposed management interfaces, particularly in regions with high usage (e.g., United States, India, Mexico). Shadowserver estimates over 11,000 exposed systems globally.

Chained Exploitation

• CVE-2024-0012 facilitates initial access, while CVE-2024-9474 is used for post-exploitation privilege escalation. Attackers deploy PHP webshells (SHA256 hash: 3C5F9034C86CB1952AA5BB07B4F77CE7D8BB5CC9FE5C029A32C72ADC7E814668) for further malicious actions.

Available Patches

• PAN-OS 10.1: Update to 10.1.14-h6 or later
• PAN-OS 10.2: Update to 10.2.12-h2 or later
• PAN-OS 11.0: Update to 11.0.6-h1 or later
• PAN-OS 11.1: Update to 11.1.5-h1 or later
• PAN-OS 11.2: Update to 11.2.4-h1 or later

Palo Alto Networks has also released patches for earlier maintenance releases frequently deployed by customers. Refer to the official advisory from Palo Alto Networks for details, here.

Workarounds and Recommendations

Mitigations

• Restrict Management Interface Access
  • Block internet-facing access. Allow access only from trusted internal IPs or secure jump boxes.
• Enable Threat Prevention
  • Apply Threat IDs (e.g., 95746 and 95747) to block exploits.

Best Practices

• Deploy administrative access best practices. Log administrative actions and monitor for anomalous configuration changes.
