CVE-2014-7344 in Classic Arms
Summary
by MITRE
The Classic Arms & Militaria (aka com.magazinecloner.classicarmsandm) application @7F080193 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-2014-7344 affects the Classic Arms & Militaria Android application, specifically targeting its implementation of secure communication protocols. This flaw resides in the application's certificate verification mechanism, which fails to properly validate X.509 certificates presented by SSL servers during secure connections. The application's failure to implement proper certificate validation creates a critical security gap that exposes users to sophisticated man-in-the-middle attacks. The vulnerability is particularly concerning because it undermines the fundamental security assurances that SSL/TLS protocols are designed to provide, allowing attackers to establish fraudulent connections that appear legitimate to the end user.
The technical implementation flaw stems from the application's complete omission of certificate pinning or proper certificate validation procedures. When an Android application establishes an SSL connection, it should verify that the server's certificate is issued by a trusted Certificate Authority and that it properly matches the expected hostname. In this case, the Classic Arms & Militaria application bypasses these essential verification steps entirely, accepting any certificate presented by the server regardless of its authenticity or trustworthiness. This behavior aligns with CWE-295, which specifically addresses the weakness of not properly validating certificates, and represents a critical failure in the application's cryptographic implementation that directly violates industry best practices for secure communication.
The operational impact of this vulnerability extends beyond simple data interception, as it enables attackers to gain unauthorized access to sensitive information that users might transmit through the application. Man-in-the-middle attackers can exploit this weakness by presenting a forged certificate that appears legitimate to the application, allowing them to decrypt and monitor all communications between the user and the server. This capability enables attackers to capture login credentials, personal information, financial data, or any other sensitive content that the application might transmit over SSL connections. The vulnerability affects all users of the application who establish secure connections with servers that are compromised or under attacker control, potentially exposing a wide range of sensitive user data and creating opportunities for identity theft, financial fraud, and other malicious activities.
Mitigation strategies for this vulnerability require immediate implementation of proper certificate validation mechanisms within the application. The recommended approach involves implementing certificate pinning, where the application explicitly trusts specific certificate authorities or specific certificate fingerprints rather than accepting any certificate from any CA. This technique, as outlined in the OWASP Mobile Security Project guidelines, ensures that even if an attacker can create a valid certificate, it will not be accepted by the application if it does not match the pre-approved certificate or public key. Additionally, the application should implement proper hostname verification procedures to ensure that certificates are only accepted for the intended domains. Security updates should include comprehensive certificate validation routines that align with industry standards such as those specified in the NIST Special Publication 800-57 and the IETF RFC 6125, which provide detailed guidance on secure certificate validation practices. Organizations should also consider implementing network monitoring to detect potential exploitation attempts and establish incident response procedures to address any confirmed breaches.
