CVE-2025-20060: Dario Health Information Disclosure Flaw

CVE-2025-20060 Overview

CVE-2025-20060 is a high-severity information disclosure vulnerability in the Dario Health Android application that could allow an attacker to expose cross-user personal identifiable information (PII) and personal health information (PHI). The vulnerability exists in the application's local database, enabling unauthorized access to sensitive medical data transmitted to Android devices.

Critical Impact

Unauthorized exposure of sensitive personal health information and PII across multiple users of the Dario Health mobile application, potentially violating HIPAA regulations and compromising patient privacy.

Technical Details for CVE-2025-20060

Vulnerability Analysis

This vulnerability is classified under CWE-359 (Exposure of Private Personal Information to an Unauthorized Actor), indicating a fundamental flaw in how the Dario Health application handles and stores sensitive user data. The vulnerability allows cross-user data exposure, meaning an attacker could potentially access PII and PHI belonging to other users of the application.

The Dario Health application, designed for managing diabetes and other chronic conditions, collects sensitive health metrics including blood glucose readings, medication information, and personal details. The vulnerability in the application's database architecture could expose this highly sensitive medical information to unauthorized parties.

Healthcare applications are subject to strict regulatory requirements under HIPAA (Health Insurance Portability and Accountability Act), making this exposure particularly concerning from both a privacy and compliance perspective.

Root Cause

The root cause stems from improper data isolation within the application's local database structure. The application fails to properly segregate user data, allowing potential cross-user access to sensitive personal and health information. This represents a violation of secure data storage principles for mobile applications handling protected health information (PHI).

Attack Vector

The vulnerability is exploitable via a network attack vector without requiring authentication or user interaction. An attacker could potentially exploit this vulnerability remotely to access the application database containing sensitive user information. The attack does not require any privileges to execute, making it particularly dangerous in healthcare environments where patient privacy is paramount.

The lack of required user interaction combined with no authentication requirements means that exploitation could occur without the victim's knowledge, potentially leading to silent data exfiltration of medical records and personal information.

Detection Methods for CVE-2025-20060

Indicators of Compromise

• Unusual database queries or access patterns within the Dario Health application data directories
• Unexpected network connections from the Dario Health application to unknown endpoints
• Evidence of database file extraction or copying from the application's private storage
• Anomalous access to the application's SQLite database files on Android devices

Detection Strategies

• Monitor Android application logs for unauthorized database access attempts
• Implement network traffic analysis to detect unusual data exfiltration from mobile health applications
• Deploy mobile device management (MDM) solutions to track application behavior anomalies
• Review access logs for the Dario Health application for signs of cross-user data access

Monitoring Recommendations

• Enable enhanced logging for mobile health applications in enterprise environments
• Monitor for bulk data access patterns that could indicate systematic data harvesting
• Implement data loss prevention (DLP) controls for protected health information on mobile devices
• Establish baseline application behavior to detect deviations that may indicate exploitation

How to Mitigate CVE-2025-20060

Immediate Actions Required

• Review the CISA Medical Advisory ICSMA-25-058-01 for official guidance
• Contact Dario Health through their official support channels for updated application versions
• Consider temporarily restricting use of the affected application until a patch is available
• Conduct a privacy impact assessment to determine if any data exposure has occurred

Patch Information

Organizations and users should monitor for security updates from Dario Health. Contact the vendor directly through their official website for the latest security patches and updated application versions. CISA has published medical advisory ICSMA-25-058-01 with additional guidance for healthcare organizations using this application.

Healthcare organizations should coordinate with their security teams and Dario Health to ensure timely deployment of any available patches while maintaining compliance with healthcare security requirements.

Workarounds

• Limit the Dario Health application to devices with enhanced security controls and MDM management
• Implement network segmentation to isolate mobile health application traffic
• Enable device encryption and secure boot on all Android devices running the application
• Consider using application containerization solutions to provide additional data isolation
• Restrict application permissions to minimum required for functionality

# Android ADB commands to verify application data protection
# Check application data directory permissions
adb shell ls -la /data/data/com.dariohealth.* 2>/dev/null

# Verify database file encryption status
adb shell sqlite3 /data/data/com.dariohealth.*/databases/*.db ".schema" 2>/dev/null

# Monitor application network activity
adb shell dumpsys netstats | grep -i dario
