Gateway HTTP

Overview

Cloudflare is a global network designed to make everything you connect to the Internet secure, private, fast, and reliable.

In this documentation, you will learn how to collect and send Cloudflare Gateway HTTP logs to Sekoia.io.

Warning

Important note - This format is currently in beta. We highly value your feedback to improve its performance.

The following Sekoia.io built-in rules match the intake Cloudflare Gateway HTTP [BETA]. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

CVE-2018-13379 Fortinet Exploit

Detects the successful exploitation of the Fortinet FortiOS CVE-2018-13379. This CVE is one of the most exploited CVEs since 2018. It is exploited by APT threat actors as well as cybercriminals. The exploitation of this CVE lead an unauthenticated user to get full access to FortiOS system file through SSL VPN via specially crafted HTTP resource requests. The exploit read /dev/cmdb/sslvpn_websession file, that contains login and passwords in (clear/text). An HTTP response status code = 200, means the file was successfully accessed. This vulnerability affects FortiOS 5.6.3 to 5.6.7 and FortiOS 6.0.0 to 6.0.4.

CVE-2019-11510 Pulse Secure Exploit

Detects the successful exploitation of the Pulse Secure vulnerability CVE-2019-11510. This CVE is one of the most exploited CVEs since 2019. It is exploited by diverse threat actors, leading sometimes in ransomware deployement. Among these groups: Maze, Conti, Egregor, DoppelPaymer, NetWalker and REvil. But also APT actors such as APT29. The exploitation of this CVE allows a remote, unauthenticated attacker to compromise a vulnerable VPN server. The attacker may be able to gain access to all active users and their plain-text credentials. It may also be possible for the attacker to execute arbitrary commands on each VPN client as it successfully connects to the VPN server. The exploit reads /etc/passwd file to get access to login and passwords in (clear/text). An HTTP response status code = 200, means the file was successfully accessed. This vulnerability affects 8.1R15.1, 8.2 before 8.2R12.1, 8.3 before 8.3R7.1, and 9.0 before 9.0R3.4 products.

With knowledge of these, values an attacker can craft a special viewstate to use an OS command to be executed by NT_AUTHORITY\SYSTEM using .NET deserialization. To exploit this vulnerability, an attacker needs to leverage the credentials of an account it had already compromised to authenticate to OWA.

Create a Logpush job

Configure a Logpush job with the following destination:

https://intake.sekoia.io/plain/batch?header_X-SEKOIAIO-INTAKE-KEY=<YOUR_INTAKE_KEY>

To do so, you can manage Logpush with cURL:

$ curl -X POST 'https://api.cloudflare.com/client/v4/accounts/<CLOUDFLARE_ACCOUNT_ID>/logpush/jobs' \
-H 'Authorization: Bearer <CLOUDFLARE_API_TOKEN>' \
-H "Content-Type: application/json" \
-d '{
    "dataset": "gateway_http",    
    "enabled": true,     
    "max_upload_bytes": 5000000,     
    "max_upload_records": 1000,
    "logpull_options":"fields=AccountID,Action,BlockedFileHash,BlockedFileName,BlockedFileReason,BlockedFileSize,BlockedFileType,Datetime,DestinationIP,DestinationPort,DeviceID,DeviceName,DownloadedFileNames,Email,FileInfo,HTTPHost,HTTPMethod,HTTPStatusCode,HTTPVersion,IsIsolated,PolicyID,PolicyName,Referer,RequestID,SourceIP,SourceInternalIP,SourcePort,URL,UntrustedCertificateAction,UploadedFileNames,UserAgent,UserID&timestamps=rfc3339",
    "destination_conf": "https://intake.sekoia.io/plain/batch?header_X-SEKOIAIO-INTAKE-KEY=<YOUR_INTAKE_KEY>"
    }' # (1)
  1. will return
    {
      "errors": [],
      "messages": [],
      "result": {
        "id": "<ID>",
        "dataset": "gateway_http",
        "frequency":"high",
        "kind":"", 
        "max_upload_bytes": 5000000,     
        "max_upload_records": 1000, 
        "enabled": true,
        "name": "<DOMAIN_NAME>",
        "logpull_options": "fields=<LIST_OF_FIELDS>",
        "destination_conf": "https://intake.sekoia.io/plain/batch?header_X-SEKOIAIO-INTAKE-KEY=<YOUR_INTAKE_KEY>",
        "last_complete": null,
        "last_error": null,
        "error_message": null,
        "time_created":"<TIMESTAMP>"
      },
      "success": true
    }
    

Important

Replace :

  • <YOUR_INTAKE_KEY> with the Intake key you generated in the Create the intake on Sekoia.io step.

  • <CLOUDFLARE_API_TOKEN> with the API Token you generated
Useful Cloudflare API endpoints

On their documentation, Cloudflare provides a list API endpoints you can use. Find below some useful endpoints:

  • https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/logpush/jobs/<JOB_ID> to verify the job you previously created is correct (you need to specify the JOB_ID)
  • https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/logpush/datasets/<DATASET>/jobs to get all the jobs for a specific dataset (dns_log, firewalls_events or http_requests in our case)
  • https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/logpush/jobs/<JOB_ID> to update a job if you noticed a mistake after the creation of the job (wrong fields, wrong SEKOIA API Key...)
