How the CVE Works:
CVE-2025-24446 exploits an improper input validation flaw in Adobe ColdFusion (versions 2023.12, 2021.18, 2025.0, and earlier). Attackers craft malicious files (e.g., CFM templates) containing arbitrary code. When a victim opens the file, ColdFusion fails to sanitize input during processing, leading to deserialization of untrusted data. This allows remote code execution (RCE) under the victim’s privileges. The attack requires user interaction but bypasses ColdFusion’s sandbox protections due to flawed validation logic in file parsing.
DailyCVE Form:
Platform: Adobe ColdFusion
Version: 2023.12, 2021.18, 2025.0
Vulnerability: RCE via Input Validation
Severity: Critical
Date: 04/15/2025
What Undercode Say:
Exploitation:
- Craft a malicious CFM file with serialized payload:
<cfset exploit = CreateObject("java", "java.lang.Runtime").getRuntime().exec("calc.exe")>
2. Deliver via phishing or compromised web uploads.
Detection:
- Log analysis for unexpected file processing:
grep -r "DeserializationException" /opt/coldfusion/logs/
Mitigation:
1. Apply Adobe’s patch immediately.
2. Restrict file uploads via ColdFusion’s `Application.cfc`:
<cfcomponent> <cffunction name="onRequestStart"> <cfif StructKeyExists(form, "fileUpload")> <cfabort showerror="Uploads disabled"> </cfif> </cffunction> </cfcomponent>
3. Use CFML sandboxing:
<sandbox> <resource-access> <file read="/tmp/" write="false"/> </resource-access> </sandbox>
Network Controls:
- Block suspicious inbound/outbound traffic:
iptables -A INPUT -p tcp --dport 8500 -m string --string "malicious.cfm" -j DROP
Forensics:
- Check runtime processes:
ps aux | grep 'coldfusion' | grep -v 'grep'
- Audit Java classes loaded by ColdFusion:
jcmd <ColdFusion_PID> VM.classloader_stats
