⚠️ Risk & Real-World Impact
Worst Case
Attackers gain unauthorized access to Druid monitoring interface, potentially accessing sensitive database metrics, executing SQL queries, or using Druid functionality to pivot to database compromise.
Likely Case
Unauthorized access to Druid monitoring dashboard exposing database performance metrics, connection information, and potentially sensitive system data.
If Mitigated
Limited impact with proper network segmentation and authentication controls preventing access to Druid interface from untrusted networks.
🎯 Exploit Status
Exploit details have been publicly disclosed in GitHub issues and vuldb.com, making this easily exploitable with minimal technical skill required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 2.8 or later
Vendor Advisory: https://github.com/elunez/eladmin/issues/883
Restart Required: Yes
Instructions:
1. Update eladmin to version 2.8 or later. 2. Verify application-prod.yml no longer contains default credentials. 3. Restart the application service. 4. Change any existing Druid credentials that may have been compromised.
🔧 Temporary Workarounds
Disable Druid Monitoring Interface
allTemporarily disable the Druid monitoring component if not required for operations.
# Edit application-prod.yml and set spring.datasource.druid.stat-view-servlet.enabled: false
# Restart application
Change Default Credentials
allManually set strong, unique credentials for Druid login in configuration.
# Edit application-prod.yml
# Change login-username and login-password to strong values
# Restart application
🧯 If You Can't Patch
- Implement network access controls to restrict access to Druid monitoring port (default 8080/druid) to trusted IPs only.
- Deploy a web application firewall (WAF) with rules to block access attempts to /druid paths with default credentials.
🔍 How to Verify
Check if Vulnerable:
Check if eladmin version is 2.7 or earlier and review application-prod.yml for default login-username/login-password values in Druid configuration section.Check Version:
Check pom.xml for version tag or application startup logs for version information.Verify Fix Applied:
Verify eladmin version is 2.8+ and attempt to access /druid path with default credentials should fail. Check that application-prod.yml contains custom, strong credentials.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts to /druid/login with default usernames
- Successful logins to Druid interface from unexpected IP addresses
- Druid access logs showing unusual query patterns
Network Indicators:
- HTTP requests to /druid paths with default credential parameters
- Port scanning activity targeting port 8080 followed by Druid access attempts
SIEM Query:
source="web_access_logs" AND (uri_path="/druid/*" AND (username="admin" OR password="123456" OR param_contains("login-username", "admin")))🔗 References
