Jenkins Arbitrary File Read CVE-2024-23897

name: Jenkins Arbitrary File Read CVE-2024-23897
id: c641260d-2b48-4eb1-b1e8-2cc5b8b99ab1
version: 8
date: '2026-03-10'
author: Michael Haag, Splunk
status: production
type: TTP
data_source:
    - Nginx Access
description: The following analytic identifies attempts to exploit Jenkins Arbitrary File Read CVE-2024-23897. It detects HTTP POST requests to Jenkins URLs containing "*/cli?remoting=false*" with a 200 status code. This activity is significant as it indicates potential unauthorized access to sensitive files on the Jenkins server, such as credentials and private keys. If confirmed malicious, this could lead to severe data breaches, unauthorized access, and further exploitation within the environment.
search: |-
    | tstats count min(_time) as firstTime max(_time) as lastTime FROM datamodel=Web
      WHERE Web.url="*/cli?remoting=false*" Web.status=200 Web.http_method=POST
      BY Web.src, Web.dest, Web.http_user_agent,

how_to_implement: This detection requires the Web datamodel to be populated from a supported Technology Add-On like Suricata, Splunk for Apache, Splunk for Nginx, or Splunk for Palo Alto. If unable to utilize the Web datamodel, modify query to your data source.
known_false_positives: False positives should be limited as this detection is based on a specific URL path and HTTP status code. Adjust the search as necessary to fit the environment.
