CVE-2014-6895 in Throne Rush
Summary
by MITRE
The Throne Rush (aka com.progrestar.bft) application 2.3.10 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The vulnerability identified as CVE-2014-6895 affects the Throne Rush Android application version 2.3.10, specifically targeting its secure communication protocols. This flaw represents a critical weakness in the application's implementation of SSL/TLS certificate validation mechanisms, creating a significant security risk for users who interact with the application's network services. The vulnerability resides in the application's failure to properly validate X.509 certificates presented by SSL servers during secure connections, which directly violates fundamental security principles for establishing trust in network communications.
The technical flaw manifests as a missing certificate verification step within the application's SSL handshake process. When the Throne Rush application establishes secure connections to its backend servers, it fails to perform proper certificate validation against trusted certificate authorities. This omission allows malicious actors to perform man-in-the-middle attacks by presenting forged certificates that appear legitimate to the vulnerable application. The certificate validation process should typically involve checking certificate signatures, verifying the certificate chain against trusted root certificates, and ensuring proper hostname matching, but these critical steps are bypassed in the affected version.
The operational impact of this vulnerability extends beyond simple data interception, as it enables attackers to completely compromise the integrity and confidentiality of communications between the mobile application and its servers. An attacker positioned between the user's device and the application's backend services can seamlessly intercept, modify, or redirect network traffic without detection. This vulnerability affects sensitive user data including personal information, login credentials, and any other data transmitted through the application's secure channels. The risk is particularly severe given that mobile applications often handle sensitive personal and financial information, making this vulnerability a prime target for cybercriminals seeking to exploit user trust in mobile gaming applications.
The vulnerability aligns with CWE-295, which specifically addresses "Improper Certificate Validation," and demonstrates characteristics consistent with ATT&CK technique T1041, which involves data compression and encryption. This flaw represents a failure in the application's security architecture and violates industry standards for mobile application security. Organizations should implement immediate mitigations including certificate pinning, proper SSL certificate validation, and regular security audits of mobile applications. The recommended approach involves updating the application to properly validate certificates against trusted CAs, implementing certificate pinning for critical connections, and conducting comprehensive security testing to ensure proper SSL/TLS implementation. Additionally, developers should follow established mobile security frameworks and guidelines to prevent similar vulnerabilities in future application releases.
