CVE-2014-7460 in Slots Heaven:FREE Slot Machine
Summary
by MITRE
The Slots Heaven:FREE Slot Machine (aka com.twelvegigs.heaven.slots) application 1.123 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-2014-7460 affects the Slots Heaven:FREE Slot Machine Android application version 1.123, representing a critical security flaw in the application's cryptographic implementation. This issue stems from the application's failure to properly validate X.509 certificates during SSL/TLS connections, creating a significant weakness in the security architecture that directly violates established cryptographic best practices. The vulnerability manifests when the application establishes secure connections to remote servers, as it accepts any certificate presented without performing the necessary verification steps that are fundamental to maintaining secure communications. This flaw places the application and its users at risk of sophisticated attack vectors that exploit the trust model inherent in secure communications protocols.
The technical implementation of this vulnerability resides in the application's SSL/TLS certificate validation mechanism, which operates under the principle of certificate pinning failure or complete absence of certificate verification. When the application attempts to establish a secure connection to a server, it should validate the server's X.509 certificate against a trusted certificate authority or implement proper certificate pinning to ensure the authenticity of the server. However, the application fails to perform these critical validation steps, allowing attackers to intercept communications and present fraudulent certificates that the application will accept as legitimate. This behavior directly corresponds to CWE-295, which specifically addresses improper certificate validation, and represents a fundamental breakdown in the application's security infrastructure. The vulnerability enables man-in-the-middle attacks where malicious actors can position themselves between the application and legitimate servers, decrypting and potentially modifying communications without detection.
The operational impact of this vulnerability extends beyond simple data interception, as it compromises the integrity and confidentiality of all communications between the application and its backend services. Attackers exploiting this vulnerability can gain access to sensitive user information including personal details, gaming activities, and potentially financial data if the application handles payment processing. The vulnerability affects all users of the affected application version, creating a widespread security risk that persists until the application is updated to properly implement certificate validation. From an attack perspective, this vulnerability aligns with ATT&CK technique T1041, which describes data compression and encryption for exfiltration, as attackers can more easily intercept and manipulate communications. The flaw essentially removes the cryptographic protection that users expect when connecting to secure services, undermining the trust model that SSL/TLS protocols are designed to establish.
Mitigation strategies for this vulnerability require immediate implementation of proper SSL/TLS certificate validation mechanisms within the application. Developers should implement certificate pinning for known good certificates or establish robust certificate chain validation that verifies certificates against trusted certificate authorities. The application must be updated to perform comprehensive X.509 certificate verification including checking certificate expiration dates, verifying certificate signatures, and ensuring certificates are issued by trusted authorities. Additionally, the application should implement proper error handling for certificate validation failures, ensuring that any certificate validation issues result in connection termination rather than acceptance of potentially fraudulent certificates. Security audits should be conducted to verify that all network communications properly implement certificate validation, and the application should be retested to confirm that the vulnerability has been fully addressed. This remediation effort aligns with industry standards such as NIST SP 800-52 for certificate management and should be part of a comprehensive mobile application security testing program to prevent similar issues in future releases.
