CVE-2014-5921 in Need for Speed Network
Summary
by MITRE
The Need for Speed Network (aka com.ea.nfsautolog.bv) application 1.0.1 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-2014-5921 affects the Need for Speed Network mobile application version 1.0.1 for Android devices, representing a critical security flaw in the application's secure communication implementation. This weakness stems from the application's failure to properly validate X.509 certificates during SSL/TLS connections, creating a significant attack surface that adversaries can exploit to compromise user data and system integrity. The vulnerability specifically targets the certificate verification mechanism that should establish trust between the mobile client and remote servers, thereby undermining the fundamental security assurances provided by Transport Layer Security protocols.
The technical flaw manifests as a complete absence of certificate validation within the application's SSL implementation, allowing attackers to present maliciously crafted certificates that would be accepted as legitimate by the vulnerable application. This represents a classic example of insufficient certificate verification, categorized under CWE-295 which specifically addresses improper certificate validation. The vulnerability operates at the application layer where SSL/TLS connections are established, and the lack of proper certificate pinning or validation creates an opportunity for man-in-the-middle attacks that fall squarely within the ATT&CK framework under T1041 for Exfiltration Over C2 Channel and T1566 for Phishing with Malicious Attachments. Attackers can exploit this weakness by intercepting network traffic and presenting forged certificates that appear authentic to the vulnerable application, thereby enabling them to decrypt and access sensitive user information transmitted over the network.
The operational impact of this vulnerability extends beyond simple data interception, as it fundamentally compromises the confidentiality and integrity of user communications within the application. Mobile users who interact with the Need for Speed Network application become susceptible to various attack vectors including credential theft, session hijacking, and data exfiltration. The vulnerability affects all users of the specific application version, regardless of their device configuration or network environment, making it particularly dangerous in public Wi-Fi scenarios where network traffic interception is more prevalent. The lack of certificate verification means that attackers can create convincing fake servers that appear legitimate to the application, potentially leading to widespread compromise of user accounts, personal information, and potentially financial data if the application handles payment-related transactions. This vulnerability essentially nullifies the security benefits of SSL/TLS encryption, rendering the application's network communications vulnerable to passive and active attacks.
Mitigation strategies for CVE-2014-5921 require immediate remediation through proper certificate validation implementation within the application's SSL/TLS stack. The most effective approach involves implementing strict certificate validation that checks certificate chains against trusted Certificate Authorities, validates certificate expiration dates, and ensures proper hostname matching. Organizations should implement certificate pinning mechanisms to prevent the acceptance of unauthorized certificates, which aligns with security best practices outlined in the OWASP Mobile Security Project. Additionally, the application should be updated to include proper error handling for certificate validation failures, ensuring that any certificate verification issues result in immediate connection termination rather than proceeding with potentially compromised communications. Security teams should also consider implementing network monitoring to detect anomalous certificate usage patterns that might indicate exploitation attempts. The vulnerability demonstrates the critical importance of proper cryptographic implementation in mobile applications and serves as a reminder that even minor oversights in security implementation can have significant consequences for user privacy and data protection.
