CVE-2025-0142: Zoom Jenkins Plugin Information Disclosure

CVE-2025-0142 Overview

CVE-2025-0142 is a cleartext storage of sensitive information vulnerability affecting the Zoom Jenkins Marketplace plugin before version 1.4. This security flaw allows an authenticated user to conduct information disclosure via network access. The vulnerability is classified under CWE-312 (Cleartext Storage of Sensitive Information), which occurs when an application stores sensitive data in plaintext within a resource that might be accessible to unauthorized parties.

Critical Impact

Authenticated attackers with network access can exploit this vulnerability to disclose sensitive information stored in cleartext by the Zoom Jenkins plugin, potentially exposing credentials, API keys, or other confidential configuration data.

Affected Products

• Zoom Jenkins Marketplace plugin versions prior to 1.4

Technical Details for CVE-2025-0142

Vulnerability Analysis

This vulnerability stems from improper handling of sensitive information within the Zoom Jenkins Marketplace plugin. The plugin stores sensitive data such as credentials, authentication tokens, or API keys in cleartext rather than using appropriate encryption or secure storage mechanisms. When sensitive information is stored without encryption, any user or process with access to the storage location can read and potentially exfiltrate this data.

Jenkins plugins often handle sensitive configuration data including credentials for integrating with external services like Zoom. When this data is stored in cleartext within Jenkins configuration files, job configurations, or logs, it becomes vulnerable to exposure through various means including direct file access, Jenkins API queries, or through build logs that may be visible to users with lower privilege levels.

Root Cause

The root cause of CVE-2025-0142 is the failure to implement proper encryption or secure credential storage for sensitive information within the Zoom Jenkins Marketplace plugin. Instead of leveraging Jenkins' built-in credentials management system or implementing proper encryption at rest, the plugin stored sensitive data in plaintext format. This design flaw violates security best practices for handling authentication credentials and sensitive configuration data in CI/CD environments.

Attack Vector

The attack vector for this vulnerability requires network access and authenticated user privileges. An attacker who has valid credentials to access the Jenkins instance can exploit this vulnerability by:

1. Navigating to plugin configuration pages or job configurations where sensitive data is stored
2. Accessing Jenkins configuration files that may contain cleartext credentials
3. Querying the Jenkins API to retrieve configuration data that includes unprotected sensitive information
4. Reviewing build logs or audit trails where sensitive data may be inadvertently exposed

Since the vulnerability requires authentication, it primarily represents a risk from insider threats, compromised accounts, or users with legitimate but limited access attempting to escalate their knowledge of sensitive credentials.

Detection Methods for CVE-2025-0142

Indicators of Compromise

• Unusual access patterns to Zoom plugin configuration pages by authenticated users
• Unexpected API queries targeting Jenkins configuration data or credentials
• Access to sensitive configuration files from unauthorized network locations
• Evidence of credential harvesting or export of Jenkins configuration data

Detection Strategies

• Monitor Jenkins access logs for unusual patterns of configuration page access
• Implement file integrity monitoring on Jenkins configuration directories
• Review Jenkins API access logs for bulk retrieval of configuration data
• Enable audit logging to track user access to plugin settings and credentials

Monitoring Recommendations

• Configure alerting for multiple failed authentication attempts followed by successful access
• Monitor for unusual export or backup operations of Jenkins configuration
• Implement network monitoring for data exfiltration patterns from Jenkins hosts
• Regularly review user access levels and remove unnecessary privileges

How to Mitigate CVE-2025-0142

Immediate Actions Required

• Upgrade the Zoom Jenkins Marketplace plugin to version 1.4 or later immediately
• Rotate any credentials or API keys that were configured in the affected plugin versions
• Review Jenkins access logs for evidence of unauthorized access to plugin configurations
• Audit user accounts with access to Jenkins and remove unnecessary privileges

Patch Information

Zoom has addressed this vulnerability in version 1.4 of the Jenkins Marketplace plugin. Organizations should update to this version or later to remediate the cleartext storage issue. After upgrading, it is essential to rotate any credentials that may have been exposed while using the vulnerable version. For detailed information about this security update, refer to the Zoom Security Bulletin ZSB-25001.

Workarounds

• Restrict network access to Jenkins instances to trusted networks only
• Implement strict role-based access control limiting who can view plugin configurations
• Use Jenkins credentials binding features to minimize direct credential exposure
• Consider temporarily disabling the Zoom plugin until the update can be applied
• Implement network segmentation to limit potential exposure scope

# Configuration example
# Update Jenkins plugin from CLI
java -jar jenkins-cli.jar -s http://your-jenkins-server/ install-plugin zoom:1.4

# Restart Jenkins to apply the update
java -jar jenkins-cli.jar -s http://your-jenkins-server/ safe-restart

# Verify plugin version after restart
java -jar jenkins-cli.jar -s http://your-jenkins-server/ list-plugins | grep zoom
