CVE-2022-25205
📋 TL;DR
This CSRF vulnerability in Jenkins dbCharts Plugin allows attackers to trick authenticated users into making unauthorized database connections via JDBC using attacker-controlled credentials. Attackers can also probe for class availability in the Jenkins instance. This affects all Jenkins instances running dbCharts Plugin version 0.5.2 or earlier.
💻 Affected Systems
- Jenkins dbCharts Plugin
📦 What is this software?
Dbcharts by Jenkins
⚠️ Risk & Real-World Impact
Worst Case
Attackers could connect Jenkins to malicious databases, potentially leading to data exfiltration, credential theft, or further exploitation through JDBC driver vulnerabilities.
Likely Case
Attackers could abuse database connections to steal sensitive data, perform reconnaissance on the Jenkins environment, or use the Jenkins instance as a pivot point for lateral movement.
If Mitigated
With proper CSRF protections and network segmentation, impact is limited to unauthorized database connections that may be detected and blocked.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users, but the technical complexity is low once user interaction is achieved.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.5.3 or later
Vendor Advisory: https://www.jenkins.io/security/advisory/2022-02-15/#SECURITY-2177
Restart Required: Yes
Instructions:
1. Update Jenkins dbCharts Plugin to version 0.5.3 or later via Jenkins Plugin Manager. 2. Restart Jenkins service after update. 3. Verify plugin version in Manage Jenkins > Manage Plugins.
🔧 Temporary Workarounds
Disable dbCharts Plugin
allTemporarily disable the vulnerable plugin until patching is possible
Navigate to Manage Jenkins > Manage Plugins > Installed tab, find dbCharts Plugin, click Disable
Enable CSRF Protection
allEnsure Jenkins CSRF protection is enabled globally
Navigate to Manage Jenkins > Configure Global Security > Enable 'Prevent Cross Site Request Forgery exploits'
🧯 If You Can't Patch
- Implement strict network segmentation to limit database connections from Jenkins instances
- Use web application firewalls (WAF) with CSRF protection rules and monitor for suspicious JDBC connection attempts
🔍 How to Verify
Check if Vulnerable:
Check installed plugin version via Manage Jenkins > Manage Plugins > Installed tab, look for dbCharts Plugin version 0.5.2 or earlierCheck Version:
curl -s http://jenkins-host/pluginManager/api/json?depth=1 | grep -o '"dbCharts":{[^}]*"version":"[^"]*"'Verify Fix Applied:
Verify dbCharts Plugin version is 0.5.3 or later in Manage Jenkins > Manage Plugins > Installed tab📡 Detection & Monitoring
Log Indicators:
- Unexpected JDBC connection attempts in Jenkins logs
- Failed authentication attempts to databases from Jenkins
- CSRF token validation failures
Network Indicators:
- Outbound database connections from Jenkins to unexpected hosts/ports
- JDBC traffic to non-standard databases
