description: The following analytic detects potential exploitation attempts against
  Adobe ColdFusion vulnerabilities CVE-2023-29298 and CVE-2023-26360. It monitors
  requests to specific ColdFusion Administrator endpoints, especially those with an
  unexpected additional forward slash, using the Web datamodel. This activity is significant
  for a SOC as it indicates attempts to bypass access controls, which can lead to
  unauthorized access to ColdFusion administration endpoints. If confirmed malicious,
  this could result in data theft, brute force attacks, or further exploitation of
  other vulnerabilities, posing a serious security risk to the environment.

how_to_implement: This detection requires the Web datamodel to be populated from a
  supported Technology Add-On like Splunk for Apache, Splunk for Nginx, or Splunk
  for Palo Alto.
known_false_positives: This analytic is limited to HTTP Status 200; adjust as necessary.
  False positives may occur if the URI path is IP-restricted or externally blocked.
  It's recommended to review the context of the alerts and adjust the analytic parameters
  to better fit the specific environment.
