CVE-2014-5634 in Martinique
Summary
by MITRE
The Madipass Martinique (aka com.goodbarber.madipassmartinique) application 1.8 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-2014-5634 affects the Madipass Martinique Android application version 1.8, representing a critical security flaw in the application's SSL/TLS certificate validation mechanism. This weakness stems from the application's failure to properly verify X.509 certificates presented by SSL servers during secure communications. The vulnerability falls under the broader category of insecure cryptographic implementation practices and can be categorized as CWE-295, which specifically addresses issues related to certificate validation and trust management. The application's improper handling of SSL certificates creates a significant attack surface that enables malicious actors to exploit the trust relationship between the client and server.
The technical flaw manifests when the Android application establishes secure connections to remote servers without performing proper certificate chain validation. This insecure implementation allows attackers to perform man-in-the-middle attacks by presenting forged certificates that appear legitimate to the application. The vulnerability specifically targets the certificate verification process, which should normally validate the certificate's authenticity through trusted certificate authorities and ensure proper certificate chain construction. When this validation is bypassed, the application accepts any certificate presented by an attacker, effectively nullifying the security benefits of SSL/TLS encryption. This weakness directly violates fundamental security principles of secure communication and authentication.
The operational impact of this vulnerability is severe and multifaceted, as it enables attackers to intercept and manipulate sensitive data transmitted between the mobile application and backend servers. An attacker positioned in the network path can present a malicious certificate to the application, causing it to establish a secure connection with the attacker's server instead of the legitimate service. This allows unauthorized access to user credentials, personal information, financial data, and other sensitive content that the application is designed to protect. The vulnerability affects the confidentiality and integrity of communications, potentially leading to identity theft, financial fraud, and data breaches. The attack vector is particularly dangerous in public network environments where such interception attacks are more easily executed, making the vulnerability exploitable in real-world scenarios.
Mitigation strategies for this vulnerability should focus on implementing proper SSL certificate validation within the application's networking layer. The recommended approach involves configuring the application to perform comprehensive certificate chain validation, including verification of certificate expiration dates, proper certificate authority signatures, and hostname matching against the server's certificate. Security measures should include implementing certificate pinning techniques to prevent the acceptance of unauthorized certificates, establishing trust in only specific certificate authorities, and ensuring the application validates the certificate chain against a trusted root certificate store. Organizations should also consider implementing certificate transparency mechanisms and regularly updating their certificate validation libraries to address known vulnerabilities in SSL/TLS implementations. This vulnerability aligns with ATT&CK technique T1041, which covers data compression and encryption, and represents a failure in the application's secure communication protocols that could be addressed through proper implementation of cryptographic best practices.
