CVE-2014-6006 in Gratta
Summary
by MITRE
The Gratta & Vinci? (aka com.dreamstep.wGrattaevinci) application 0.21.13167.93474 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 described in CVE-2014-6006 represents a critical security flaw in the Gratta & Vinci Android application version 0.21.13167.93474 which exposes users to significant man-in-the-middle attack risks. This application fails to properly validate X.509 certificates during SSL/TLS connections, creating a dangerous gap in the cryptographic security infrastructure that adversaries can exploit to intercept and manipulate sensitive data communications.
The technical flaw manifests as a complete absence of certificate verification mechanisms within the application's SSL implementation. When the application establishes secure connections to remote servers, it does not perform the essential validation steps required to confirm certificate authenticity, including checking certificate chains, verifying digital signatures, and ensuring certificates have not been revoked. This deficiency directly violates fundamental security principles outlined in industry standards such as CWE-295 which specifically addresses "Improper Certificate Validation" and CWE-310 which covers "Cryptographic Issues" in mobile applications. The vulnerability creates a trust relationship that can be easily subverted by attackers who can present fraudulent certificates that appear legitimate to the application.
The operational impact of this vulnerability extends beyond simple data interception to encompass complete session hijacking capabilities for attackers. When users engage with the application, any sensitive information transmitted through SSL connections becomes vulnerable to theft including personal data, login credentials, financial information, and other confidential communications. The attack vector is particularly dangerous in public Wi-Fi environments or compromised networks where attackers can easily position themselves between the client and server to present malicious certificates. This vulnerability directly maps to ATT&CK technique T1041 which describes "Exfiltration Over Command and Control Channel" and T1566 which covers "Phishing for Information" through credential theft mechanisms that become possible due to the weakened security posture.
Mitigation strategies for this vulnerability must address both immediate application-level fixes and broader security architecture improvements. The primary recommendation involves implementing proper certificate pinning mechanisms that validate certificate chains against known good certificates or public key fingerprints rather than relying on the default trust store validation. Additionally, the application should implement certificate verification routines that check certificate expiration dates, validate certificate authorities, and ensure certificate subject names match expected domain names. Organizations should also consider implementing network-level monitoring to detect anomalous certificate behavior and establish secure communication protocols that enforce strict certificate validation requirements. The solution must align with security frameworks such as NIST SP 800-52 which provides guidelines for certificate selection and management, and should be integrated with mobile security solutions that can monitor and enforce secure communication practices across all application components.
