How the CVE Works:
CVE-2025-31727 affects Jenkins AsakusaSatellite Plugin versions 0.1.1 and earlier. The vulnerability stems from improper storage of AsakusaSatellite API keys in job `config.xml` files on the Jenkins controller. These keys are stored unencrypted, allowing unauthorized access via:
1. File System Access: Attackers with read permissions on the Jenkins controller can extract API keys.
2. Item/Extended Read Permissions: Jenkins users with these permissions can view the keys in job configurations.
The exposed API keys could enable further attacks, such as unauthorized API calls or integration breaches.
DailyCVE Form:
Platform: Jenkins
Version: ≤ 0.1.1
Vulnerability: Sensitive Data Exposure
Severity: Medium
Date: 04/17/2025
What Undercode Say:
Exploitation:
1. Extract API Keys via File System:
grep -r "asakusa_api_key" /var/lib/jenkins/jobs/
2. Exploit via Jenkins API:
import requests
jenkins_url = "http://target/job/config.xml"
response = requests.get(jenkins_url, auth=('user', 'pass'))
print(response.text)
Mitigation:
1. Upgrade Plugin:
jenkins-plugin-cli --update asakusa-satellite
2. Encrypt Secrets: Use Jenkins Credentials Plugin:
credentials {
string(credentialsId: 'asakusa_key', variable: 'API_KEY')
}
3. Restrict Permissions:
chmod 600 /var/lib/jenkins/jobs//config.xml
Detection:
1. Audit Config Files:
find /var/lib/jenkins -name "config.xml" -exec grep -l "asakusa_api_key" {} \;
2. Jenkins Script Console Check:
Jenkins.instance.pluginManager.plugins.each {
if (it.shortName == "asakusa-satellite" && it.version <= "0.1.1") {
println("Vulnerable plugin detected: ${it.getDisplayName()}")
}
}
Analytics:
- Impact: Data leakage, privilege escalation.
- Attack Vector: Local/remote (depending on permissions).
- Patch: Update to AsakusaSatellite Plugin > 0.1.1.
