CyberRota Analysis
AI-GeneratedThe vulnerability allows unauthorized generation of physical access QR codes due to hard-coded credentials within the application, specifically leveraging the static 'badge_number' parameter as the HMAC private key. Attackers can exploit this flaw by accessing the API endpoint and reverse engineering the APK, enabling them to create valid QR codes indefinitely, regardless of user authentication changes. Organizations using this application should prioritize remediation to prevent unauthorized access and potential security breaches.
Original NVD Description
The vulnerability allows the unauthorised generation of physical access QR codes due to the use of hard-coded credentials within the application. The generation mechanism uses the 'badge_number' parameter as the HMAC private key, the value of which remains static and is accessible via the API using the endpoint '/club/_id_club_/member/_id_member_/resamania_qr_info'. An attacker with access to this value and to the application’s cryptographic logic, which can be extracted by reverse engineering the APK as there is no code obfuscation, could generate valid QR codes indefinitely, even after the user has changed their password or logged out.
