CVE-2025-53670
📋 TL;DR
The Jenkins Nouvola DiveCloud Plugin 1.08 and earlier stores sensitive API keys and encryption keys unencrypted in job configuration files. This allows users with Item/Extended Read permission or filesystem access to view these credentials, potentially leading to unauthorized access to DiveCloud services. Organizations using the vulnerable plugin versions are affected.
💻 Affected Systems
- Jenkins Nouvola DiveCloud Plugin
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain access to DiveCloud API keys, allowing them to manipulate cloud resources, exfiltrate sensitive data, or disrupt services connected to those credentials.
Likely Case
Internal users with read permissions or compromised Jenkins instances expose API keys, leading to unauthorized API calls or credential misuse.
If Mitigated
With proper access controls and monitoring, exposure is limited to authorized personnel only, minimizing misuse potential.
🎯 Exploit Status
Exploitation requires Item/Extended Read permission or filesystem access; no authentication bypass needed beyond those permissions.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.09 or later
Vendor Advisory: https://www.jenkins.io/security/advisory/2025-07-09/#SECURITY-3526
Restart Required: Yes
Instructions:
1. Update Jenkins Nouvola DiveCloud Plugin to version 1.09 or later via Jenkins Plugin Manager. 2. Restart Jenkins to apply changes. 3. Review and update any stored DiveCloud credentials if necessary.
🔧 Temporary Workarounds
Restrict Item/Extended Read Permissions
allLimit users with Item/Extended Read permission to only trusted administrators to prevent credential exposure.
Configure via Jenkins Manage Jenkins > Configure Global Security > Project-based Matrix Authorization Strategy
Filesystem Access Control
linuxRestrict filesystem access to Jenkins controller directories containing config.xml files to prevent unauthorized viewing.
chmod 600 /var/lib/jenkins/jobs/*/config.xml
setfacl -m u:jenkins:rw /var/lib/jenkins/jobs/*/config.xml
🧯 If You Can't Patch
- Remove DiveCloud credentials from existing jobs and store them securely outside Jenkins.
- Audit and monitor access to Jenkins job configuration files and API key usage in DiveCloud.
🔍 How to Verify
Check if Vulnerable:
Check plugin version in Jenkins Manage Jenkins > Plugin Manager > Installed plugins for 'Nouvola DiveCloud Plugin' version 1.08 or earlier.Check Version:
grep -r 'Nouvola DiveCloud' /var/lib/jenkins/plugins/*/META-INF/MANIFEST.MF | grep 'Plugin-Version'Verify Fix Applied:
Verify plugin version is 1.09 or later in Plugin Manager and check that DiveCloud credentials are no longer stored in plaintext in job config.xml files.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to Jenkins job configuration files or DiveCloud API logs showing unexpected activity from Jenkins IPs.
Network Indicators:
- Unusual outbound connections from Jenkins server to DiveCloud API endpoints at unexpected times.
SIEM Query:
source="jenkins.log" AND ("config.xml" OR "DiveCloud") AND ("access denied" OR "unauthorized")
