Detection guidance
ColdFusion Server Process Spawning Command Shell
A behavioural hunt for the technique in general, not a signature for the CVEs this report names.
Detects the ColdFusion Java process spawning a command interpreter or scripting engine, a common post-exploitation pattern following abuse of input validation / RCE flaws such as CVE-2025-61809. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.
title: ColdFusion Server Process Spawning Command Shell
id: cc059b36-3b6b-50e7-a5cf-2fab5a4b1259
status: experimental
description: Detects ColdFusion or its underlying Java/JRun process spawning cmd.exe,
powershell.exe, or other script interpreters, which is consistent with exploitation
of ColdFusion input validation/RCE vulnerabilities (e.g. CVE-2025-61809) leading
to command execution.

Web Shell File Dropped by ColdFusion Process
A behavioural hunt for the technique in general, not a signature for the CVEs this report names.
Detects creation of script/executable files (jsp, cfm, cfc, php, aspx, exe) by the ColdFusion service account/process in web-accessible directories, indicative of webshell deployment following exploitation of a ColdFusion vulnerability such as CVE-2025-61809. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply) and live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
