CVE-2014-6867 in Sortir en Alsace
Summary
by MITRE
The Sortir en Alsace (aka com.axessweb.sortirenalsace) application 0.5b 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-2014-6867 affects the Sortir en Alsace Android application version 0.5b, representing a critical security flaw in the application's secure communication implementation. This issue 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 impacts the application's cryptographic security mechanisms, which are essential for maintaining confidential communication between the mobile client and remote servers.
The technical flaw manifests as a missing certificate verification process within the application's SSL implementation, directly violating fundamental security principles for secure communications. According to CWE-295, this represents a weakness in certificate validation where the application fails to properly validate the authenticity and trustworthiness of SSL certificates presented by servers. The vulnerability allows attackers to perform man-in-the-middle attacks by presenting forged certificates that appear legitimate to the application, enabling them to intercept, modify, or steal sensitive data transmitted between the mobile application and its backend services. This flaw fundamentally undermines the SSL/TLS security model that is designed to prevent such interception attacks.
The operational impact of this vulnerability extends beyond simple data theft, as it enables attackers to establish persistent unauthorized access to user accounts and sensitive information. Mobile applications that rely on secure communication channels for user authentication, personal data handling, or financial transactions become particularly vulnerable when they fail to properly validate SSL certificates. The attack vector allows adversaries to create convincing fake servers that the application will trust, potentially leading to credential theft, session hijacking, and unauthorized access to user accounts. This vulnerability particularly affects applications that handle personal information, user credentials, or financial data, making it a significant concern for privacy and security.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1573.002 for "Reversible Encryption" and T1046 for "Network Service Scanning" as attackers can establish persistent monitoring capabilities. The vulnerability creates opportunities for attackers to establish backdoors through compromised communication channels, potentially enabling long-term surveillance of user activities. Security professionals should consider this vulnerability as part of a broader threat landscape where mobile applications are increasingly targeted due to their often-limited security implementation compared to traditional desktop applications. Organizations should implement comprehensive security testing including certificate pinning verification, secure coding practices, and regular security audits to prevent similar vulnerabilities in mobile application development. The vulnerability underscores the critical importance of proper cryptographic implementation and certificate validation in mobile applications, as highlighted in industry best practices such as those outlined in the OWASP Mobile Security Project and NIST guidelines for mobile application security.
