CVE-2025-56466: Dietly Information Disclosure Flaw

CVE-2025-56466 Overview

A hardcoded credentials vulnerability has been identified in Dietly version 1.25.0 for Android, a mobile application developed by MasterlifeCRM. This security flaw allows attackers to gain access to sensitive information by exploiting credentials that have been embedded directly within the application's source code or configuration files.

Hardcoded credentials represent a significant security risk as they cannot be easily rotated or revoked, and once discovered, provide persistent unauthorized access to protected resources. The network-accessible nature of this vulnerability means remote attackers can potentially extract and abuse these credentials without requiring any user interaction or prior authentication.

Critical Impact

Attackers can extract hardcoded credentials from the Dietly Android application to gain unauthorized access to sensitive user data and backend systems, potentially compromising confidentiality across the entire user base.

Affected Products

• MasterlifeCRM Dietly v1.25.0 for Android (cpe:2.3:a:masterlifecrm:dietly:1.25.0:*:*:*:*:android:*:*)

Technical Details for CVE-2025-56466

Vulnerability Analysis

This vulnerability falls under CWE-798 (Use of Hard-coded Credentials), a well-documented security weakness where authentication credentials such as passwords, API keys, or cryptographic keys are embedded directly within application code or configuration files. In the context of Android applications like Dietly, these credentials can be stored in various locations including Java/Kotlin source code, shared preferences, resources files, or native libraries.

The attack can be executed over the network without requiring any privileges or user interaction. The vulnerability exclusively impacts confidentiality, allowing attackers to access sensitive information without affecting the integrity or availability of the system.

Root Cause

The root cause of CVE-2025-56466 stems from insecure development practices where sensitive credentials were embedded directly into the Dietly Android application. This commonly occurs when developers hardcode API keys, database credentials, authentication tokens, or encryption keys for convenience during development and fail to remove or externalize them before production deployment.

Android APK files can be easily decompiled using tools like apktool, jadx, or dex2jar, allowing attackers to reverse engineer the application and extract any hardcoded secrets. Once extracted, these credentials can be used to authenticate to backend services, access user data, or escalate privileges within the application ecosystem.

Attack Vector

The attack vector for this vulnerability involves the following exploitation chain:

1. An attacker downloads the Dietly v1.25.0 APK from the Google Play Store or third-party sources
2. The APK is decompiled using standard Android reverse engineering tools
3. Static analysis is performed to identify hardcoded credentials within the decompiled source code, resources, or configuration files
4. The extracted credentials are used to authenticate to backend services or APIs
5. Sensitive user information becomes accessible to the attacker

Detection Methods for CVE-2025-56466

Indicators of Compromise

• Unusual API access patterns or authentication attempts from unexpected IP addresses using legitimate credentials
• Multiple simultaneous sessions using the same service account or API key from different geographic locations
• Backend service logs showing credential usage that doesn't correlate with legitimate mobile app traffic patterns
• Detection of Dietly v1.25.0 APK decompilation tools or reverse engineering activity in enterprise environments

Detection Strategies

• Implement API monitoring to detect anomalous usage patterns associated with the hardcoded credentials
• Deploy mobile application security scanning tools to identify hardcoded secrets in APK files across your organization
• Monitor authentication logs for backend services that Dietly connects to for suspicious access patterns
• Use network traffic analysis to identify unauthorized access attempts to Dietly's backend infrastructure

Monitoring Recommendations

• Enable detailed logging on all backend services and APIs that Dietly authenticates against
• Implement rate limiting and geo-fencing on sensitive API endpoints to detect and block credential abuse
• Deploy SentinelOne Singularity Mobile to detect compromised or vulnerable mobile applications in your environment
• Establish baseline behavioral profiles for legitimate Dietly application traffic to identify anomalies

How to Mitigate CVE-2025-56466

Immediate Actions Required

• Identify if Dietly v1.25.0 is installed on any managed mobile devices within your organization
• Assume any credentials hardcoded in the affected version have been compromised and initiate credential rotation
• Contact MasterlifeCRM to inquire about patched versions and update timelines
• Implement additional monitoring on backend systems that integrate with Dietly

Patch Information

As of the last NVD update on 2025-10-06, no official patch information has been published by MasterlifeCRM. Organizations should monitor the vendor's official channels and the GitHub security research page for updates on remediation guidance.

Users are advised to update to the latest version of Dietly when a patched release becomes available. In the meantime, implementing compensating controls on backend services is recommended.

Workarounds

• Restrict or block network access from Dietly v1.25.0 installations until a patched version is available
• Implement additional authentication factors on backend services beyond the compromised credentials
• Deploy web application firewalls (WAF) or API gateways with behavioral analysis to detect credential abuse
• Use mobile device management (MDM) solutions to enforce application version policies and block vulnerable versions
