CVE-2014-6932 in All Navalny
Summary
by MITRE
The All Navalny (aka com.all.navalny) application 1.10 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-2014-6932 affects the All Navalny Android application version 1.10, presenting a critical security flaw in the application's secure communication implementation. This weakness resides in the application's failure to properly validate X.509 certificates during SSL/TLS connections, creating a significant attack vector for malicious actors seeking to compromise user data integrity and confidentiality. The vulnerability specifically targets the certificate verification process that should occur during secure network communications between the mobile application and remote servers, fundamentally undermining the security assurances that SSL/TLS protocols are designed to provide.
The technical flaw manifests as a complete absence of certificate validation mechanisms within the application's network security implementation. When the All Navalny application establishes connections to remote servers using SSL/TLS encryption, it fails to perform the essential step of verifying the server's X.509 certificate against trusted certificate authorities. This omission allows attackers to intercept communications through man-in-the-middle attacks where they can present fraudulent certificates that the application will accept without question. The vulnerability directly maps to CWE-295, which specifically addresses "Improper Certificate Validation," and represents a fundamental breakdown in the application's security architecture that violates established security best practices.
The operational impact of this vulnerability extends beyond simple data interception, creating potential pathways for comprehensive data theft and system compromise. Attackers can exploit this weakness to obtain sensitive user information including personal data, login credentials, and any other information transmitted through the application's network connections. The vulnerability particularly affects users who rely on the application for accessing navalny-related content, potentially exposing them to targeted attacks aimed at compromising their communications and privacy. This weakness creates an environment where attackers can establish false trust relationships with the application, allowing them to monitor, modify, or steal all data transmitted between the user's device and the application's servers.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security architecture improvements. The primary solution involves implementing proper certificate validation mechanisms that verify server certificates against trusted certificate authorities, including certificate pinning where appropriate for critical applications. Security professionals should recommend that developers implement certificate validation checks that verify certificate chains, expiration dates, and trust relationships before establishing secure connections. Organizations should also consider implementing network monitoring to detect potential man-in-the-middle attacks and establish incident response procedures for addressing certificate-related security incidents. This vulnerability demonstrates the critical importance of following established security frameworks such as those outlined in the OWASP Mobile Security Project and aligns with ATT&CK technique T1046 for Network Service Scanning, emphasizing the need for comprehensive mobile application security testing and validation.
