Lifecycle Timeline
4DescriptionCVE.org
A vulnerability was determined in Dialogue App up to 4.3.2 on Android. The affected element is an unknown function of the file file res/raw/config.json of the component ca.diagram.dialogue. Executing a manipulation of the argument SEGMENT_WRITE_KEY can lead to use of hard-coded cryptographic key . The attack is restricted to local execution. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Dialogue App versions 4.3.0 through 4.3.2 on Android use a hard-coded cryptographic key in the SEGMENT_WRITE_KEY parameter within res/raw/config.json, allowing local authenticated attackers to perform unauthorized data injection and user profile manipulation on the device. The vulnerability has a CVSS score of 1.9 (minimal severity) but publicly available exploit code exists; however, the low CVSS score reflects the local-only attack vector and limited impact scope. The vendor has not responded to early disclosure notifications.
Technical ContextAI
The vulnerability stems from CWE-321 (Use of Hard-Coded Cryptographic Key), a fundamental cryptographic hygiene failure where sensitive key material is embedded in application resources rather than derived or securely provisioned. The affected component ca.diagram.dialogue in Dialogue App reads configuration from res/raw/config.json, which is part of the Android APK's static resources-directly accessible to any process with local file access on the device. The SEGMENT_WRITE_KEY parameter, likely used for client-side event tracking or analytics integration, is hard-coded and thus compromised. Local authenticated users (PR:L in CVSS vector) can manipulate this argument through standard Android file or intent-based attacks, enabling them to forge or inject data using the embedded key material.
RemediationAI
No vendor-released patch identified at time of analysis. The vendor did not respond to early disclosure and no updated version is available. Mitigation options are limited to administrative or operational controls: (1) restrict app installation and use to low-risk endpoints where local attacker presence is unlikely; (2) use mobile device management (MDM) to enforce app version pinning or removal if the app is not critical to business operations; (3) monitor for suspicious local activity on devices running Dialogue App that could indicate exploitation; (4) if available, contact the vendor directly or escalate through app store channels to request security remediation. Users should consider uninstalling the app if an alternative with better cryptographic practices is available.
