Summary

The vulnerability allows unauthorized 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, 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.

Risk Assessment

An attacker can gain physical access to facilities or systems by generating valid QR codes, compromising physical security and access control integrity.

Recommendation

Change the QR code generation mechanism to use dynamic, secure keys, and apply code obfuscation and enforce credential rotation.
