Title
La Nacion App app.lanacion.activity BuildConfig.java credentials storage
Summary
A weakness has been identified in La Nacion App 10.2.25 on Android. This impacts an unknown function of the file source/app/lanacion/clublanacion/BuildConfig.java of the component app.lanacion.activity. Executing a manipulation of the argument API_KEY_WEBSOCKET_CV can lead to unprotected storage of credentials. The attack can only be executed locally. A high complexity level is associated with this attack. The exploitability is said to be difficult. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
