1. Introduction
The “Good MDM Data Collect” vulnerability involves gathering information about devices managed by Good Mobile Device Management (MDM). This is important because it allows administrators to understand their device inventory and ensure compliance with security policies. Affected systems are typically those running the Good MDM client software. A successful exploit could allow an attacker to identify managed devices, potentially leading to further reconnaissance or targeted attacks. Confidentiality of device information may be compromised.
2. Technical Explanation
This plugin requests device information from the Good MDM system and stores it for future reporting. The vulnerability lies in the collection and storage of this data without explicit user consent or robust security measures. An attacker with access to the system could potentially retrieve sensitive device details. There is no known CVE associated with this specific data collection process, but it represents a potential information disclosure risk.
- Root cause: The plugin collects and stores Good MDM device information without sufficient security controls.
- Exploit mechanism: An attacker gains access to the system where the plugin runs and retrieves the stored device data.
- Scope: Systems running the Good MDM client software and any systems storing the collected data are affected.
3. Detection and Assessment
To confirm if a system is vulnerable, check for the presence of the plugin and review its configuration. A thorough method involves examining logs for evidence of data collection.
- Quick checks: Check for the existence of the plugin installation directory or related processes.
- Scanning: No specific signature IDs are available for this vulnerability.
- Logs and evidence: Examine application logs for entries related to Good MDM device information collection.
4. Solution / Remediation Steps
The following steps outline how to address the vulnerability.
4.1 Preparation
- Ensure you have access to restore the previous configuration if needed. A roll back plan involves restoring the backed-up configuration files.
- Change windows may be required depending on your environment and approval processes.
4.2 Implementation
- Step 1: Review the plugin’s data collection settings to ensure only necessary information is collected.
- Step 2: Implement appropriate access controls to restrict access to the stored device data.
- Step 3: Enable logging and monitoring for any unauthorized access attempts.

4.4 Security Practices Relevant to This Vulnerability
Several security practices can help prevent this type of issue.
- Practice 1: Least privilege – limit access to sensitive data to only authorized personnel.
4.5 Automation (Optional)
5. Verification / Validation
Confirm the fix by verifying access controls and reviewing logs for unauthorized activity.
- Post-fix check: Verify that only authorized users can access the stored device data.
- Re-test: Attempt to retrieve device data with an unauthorized account to confirm access is restricted.
- Smoke test: Ensure that core MDM functionality, such as device enrollment and policy updates, continues to work as expected.
- Monitoring: Monitor application logs for any failed access attempts or suspicious activity related to Good MDM data collection.
6. Preventive Measures and Monitoring
Implement security baselines and monitoring practices to prevent similar issues.
- Baselines: Update your security baseline to include requirements for data collection and access control.
- Asset and patch process: Establish a regular review cycle for configuration files and security settings.
7. Risks, Side Effects, and Roll Back
Be aware of potential risks associated with the change.
- Risk or side effect 1: Restricting access to data may impact legitimate users who require it. Ensure proper documentation and training are provided.
- Roll back: Restore the backed-up configuration files if any issues arise during implementation.
