CVE-2014-7069 in Brand
Summary
by MITRE
The Aventino Brand (aka com.AventinoBrand) application 2.2 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-2014-7069 affects the Aventino Brand Android application version 2.2, representing a critical security flaw in the application's cryptographic implementation. This weakness resides in the application's failure to properly validate X.509 certificates during SSL/TLS connections, creating a significant attack vector that compromises the integrity of secure communications between the mobile client and remote servers. The vulnerability directly impacts the application's ability to establish trust relationships with backend services, potentially exposing users to sophisticated man-in-the-middle attacks that can intercept or manipulate sensitive data flows.
The technical flaw manifests as a complete absence of certificate validation mechanisms within the application's SSL implementation. When the Android application establishes secure connections to servers, it fails to perform the essential certificate verification steps that should confirm the authenticity of server certificates against trusted Certificate Authority roots. This omission creates a scenario where attackers can present maliciously crafted certificates that appear legitimate to the vulnerable application, effectively bypassing the security controls that should protect against unauthorized access and data interception. The vulnerability aligns with CWE-295, which specifically addresses "Improper Certificate Validation," and represents a fundamental failure in the application's security architecture.
The operational impact of this vulnerability extends beyond simple data interception to encompass comprehensive security compromise of user communications and sensitive information processing. Attackers can exploit this weakness to perform man-in-the-middle attacks, where they position themselves between the application and legitimate servers to capture, modify, or redirect communications. This capability enables unauthorized access to user credentials, personal information, financial data, and other sensitive content that the application processes or stores. The vulnerability particularly affects applications handling authentication tokens, user profiles, payment information, and confidential business data, making it a severe concern for enterprise security and user privacy protection.
Organizations and developers should implement immediate mitigations to address this vulnerability by incorporating proper certificate validation mechanisms into the application's SSL/TLS implementation. The recommended approach involves enabling certificate pinning, implementing robust certificate chain validation, and ensuring that the application verifies certificate signatures against trusted root certificates. Security controls should include implementing certificate validation checks that verify certificate expiration dates, ensure certificate chains are properly formed, and confirm that certificates are issued by trusted Certificate Authorities. This vulnerability demonstrates the critical importance of following security best practices such as those outlined in the OWASP Mobile Security Project and aligns with ATT&CK technique T1041, which covers data manipulation through man-in-the-middle attacks. The remediation efforts should also include regular security testing, including penetration testing and vulnerability assessments, to identify and address similar cryptographic weaknesses in mobile applications.
