CVE-2025-56466: Dietly Information Disclosure Flaw

CVE-2025-56466 Overview

CVE-2025-56466 affects the Dietly Android application version 1.25.0 published by Masterlifecrm. The vulnerability stems from hardcoded credentials embedded directly within the application package [CWE-798]. Attackers who extract and reverse engineer the APK can recover these static secrets without authentication. The exposed credentials enable unauthorized access to sensitive information processed by the application. The flaw is exploitable over the network without user interaction, making it accessible to remote attackers who obtain the application binary.

Critical Impact

Static credentials embedded in the Dietly Android app allow remote attackers to retrieve sensitive information from backend services without authenticating as a legitimate user.

Affected Products

• Masterlifecrm Dietly version 1.25.0 (Android)
• Android client builds shipping the embedded credential strings
• Backend services trusting the hardcoded credentials

Discovery Timeline

• 2025-09-10 - CVE-2025-56466 published to the National Vulnerability Database (NVD)

Technical Details for CVE-2025-56466

Vulnerability Analysis

The Dietly Android application ships with credentials compiled into the distributed APK. Hardcoded credentials [CWE-798] are static authentication values stored within source code, resource files, or compiled binaries. Any party with access to the application package can recover the secrets through standard reverse engineering workflows.

Attackers typically extract the APK from a device or public application repository. Tools such as apktool, jadx, and strings reveal embedded keys, tokens, and credential pairs within the decompiled output. Once recovered, the credentials remain valid for every installation because they are not user-specific or rotated per session.

The disclosed information can include API keys, service account credentials, or backend authentication tokens. The published CVSS vector indicates network-based exploitation with high confidentiality impact and no impact to integrity or availability. The EPSS probability is 0.046% at the 14.254 percentile, reflecting limited observed exploitation activity to date.

Root Cause

The root cause is the inclusion of static authentication material inside the shipped Android application instead of retrieving secrets at runtime through an authenticated user session. Mobile binaries are client-side artifacts and must be treated as fully untrusted, since any embedded value is recoverable.

Attack Vector

An attacker downloads the Dietly APK, decompiles it, and locates the embedded credentials. The attacker then issues requests directly to the backend service using the recovered credentials. No interaction with a legitimate Dietly user is required, and the exploit can be performed from any internet-connected host.

Detection Methods for CVE-2025-56466

Indicators of Compromise

• Backend API requests that present the hardcoded credentials from source IP addresses inconsistent with normal mobile client traffic
• Authentication events using the embedded credentials outside expected Dietly application user agents
• Bulk or automated queries against backend endpoints returning user data

Detection Strategies

• Inspect Dietly application traffic for the static credential identifiers and alert when they originate from non-mobile hosts
• Perform binary analysis of installed dietly APKs to confirm version 1.25.0 is no longer present on managed devices
• Correlate backend access logs against expected geographic and device fingerprint distributions to flag anomalies

Monitoring Recommendations

• Log all authentication attempts that use the embedded credential identifiers and review for volume spikes
• Monitor mobile device management (MDM) inventories for the vulnerable Dietly version
• Track outbound requests to Dietly backend hostnames from non-mobile network segments

How to Mitigate CVE-2025-56466

Immediate Actions Required

• Rotate or invalidate the credentials embedded in Dietly version 1.25.0 at the backend service
• Block backend authentication using the leaked credential values and force a server-side credential refresh
• Remove Dietly version 1.25.0 from managed Android devices until the vendor publishes a fixed release

Patch Information

No vendor advisory or fixed version is listed in the NVD record at the time of publication. Contact Masterlifecrm directly to confirm patch availability and consult the CVE-2025-56466 research notes for additional technical context.

Workarounds

• Restrict backend acceptance of the hardcoded credentials at the API gateway and require per-user authentication tokens
• Apply network-level rate limiting and anomaly detection on Dietly API endpoints to slow credential abuse
• Communicate the risk to end users and instruct them to uninstall the affected version until a patched build is released

# Configuration example
# Revoke the leaked credential at the API gateway (illustrative)
revoke-credential --service dietly-api --credential-id <hardcoded-id>
deny-rule add --service dietly-api --match-header "Authorization: <leaked-token>" --action block
