• Physical Access: Requires physical access to the device to enter Safe Mode.

Exploitation Methods:

• Entering Safe Mode: The child can reboot the device into Safe Mode, which disables third-party applications, including the Boomerang Parental Control app.
• Uninstalling the Application: Once in Safe Mode, the child can uninstall the Boomerang app without the parent being notified.
• Temporary Bypass: The child can temporarily bypass restrictions by disabling the app in Safe Mode and then re-enabling it after use.

3. Affected Systems and Software Versions

Affected Systems:

• Android devices running the Boomerang Parental Control application.

Software Versions:

• Boomerang Parental Control for Android versions up to 13.83.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Update the Application: Ensure that the Boomerang Parental Control application is updated to the latest version that addresses this vulnerability.
• Monitor Device Usage: Regularly check the device for any signs of tampering or unauthorized changes.

Long-Term Mitigation:

• Enhanced Safe Mode Protection: Implement mechanisms to prevent the app from being disabled in Safe Mode.
• Notification Systems: Develop notification systems to alert parents if the app is uninstalled or disabled.
• Regular Audits: Conduct regular security audits and penetration testing to identify and mitigate similar vulnerabilities.

5. Impact on Cybersecurity Landscape

Immediate Impact:

• Loss of Control: Parents lose control over their children's device usage, potentially exposing children to inappropriate content or activities.
• Trust Issues: Undermines the trust in parental control applications, leading to potential abandonment of such tools.
