Official description
An issue was discovered in the A4N (Aremis 4 Nomad) application 1.5.0 for Android. It possesses an authentication mechanism; however, some features do not require any token or cookie in a request. Therefore, an attacker may send a simple HTTP request to the right endpoint, and obtain authorization to retrieve application data.
