CVE-2014-5815

Vulnerability

The Solitaire Arena application (com.mavenhut.solitaire) version 1.0.15 for Android does not properly verify X.509 certificates from SSL servers. This means that when the app establishes an HTTPS connection, it accepts any certificate presented without validating the chain of trust against a trusted root certificate authority [1]. The vulnerability affects all HTTPS communications made by the app.

Exploitation

An attacker positioned on the same network as the victim (e.g., a public Wi-Fi hotspot) can perform a man-in-the-middle attack. The attacker intercepts the HTTPS traffic and presents a crafted certificate to the app. Because the app does not validate the certificate, it accepts the attacker's certificate and establishes an encrypted session with the attacker instead of the legitimate server [1]. No user interaction beyond normal app usage is required.

Impact

A successful attacker can view and modify network traffic that should have been protected by HTTPS. This can lead to the disclosure of sensitive information such as login credentials, personal data, or financial details. Depending on the app's functionality, the impact may extend to arbitrary code execution [1]. The compromise occurs at the network level, affecting all data transmitted by the app.

Mitigation

As of the publication date (2014-09-09), no official patch has been released for Solitaire Arena version 1.0.15. The CERT/CC recommends avoiding the use of affected applications for sensitive transactions and instead accessing the same services through a web browser, which typically implements proper SSL validation [1]. Users should uninstall the app or refrain from using it until a fix is provided.
