CVE-2014-6902 in Anjuke
Summary
by MITRE
The Anjuke (aka com.anjuke.android.app) application 7.1.7 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-2014-6902 affects the Anjuke mobile application version 7.1.7 for Android platforms, representing a critical security flaw in the application's implementation of secure communication protocols. 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 integrity and confidentiality. The vulnerability directly impacts the application's ability to establish trust with remote servers, fundamentally undermining the security assurances that SSL/TLS protocols are designed to provide.
The technical flaw manifests in the application's certificate verification process where it fails to perform proper validation of X.509 certificates presented by SSL servers. This omission allows attackers to perform man-in-the-middle attacks by presenting fraudulent certificates that appear legitimate to the vulnerable application. The application accepts these malicious certificates without proper scrutiny, enabling attackers to intercept, modify, or steal sensitive information transmitted between the mobile device and targeted servers. This weakness aligns with CWE-295, which specifically addresses improper certificate validation in secure communications, and represents a classic example of insufficient certificate, key, and trust validation that leaves applications vulnerable to cryptographic attacks.
The operational impact of this vulnerability extends beyond simple data interception, as it enables comprehensive surveillance and data manipulation capabilities for attackers. Mobile users of the Anjuke application become susceptible to various attack vectors including credential theft, session hijacking, and sensitive information disclosure. The vulnerability particularly affects users who rely on the application for financial transactions, personal data management, or other sensitive activities, as attackers can exploit this flaw to gain unauthorized access to user accounts and private information. The implications are severe given that the application operates on mobile devices where users may be accessing sensitive data over unsecured networks, making the attack surface even more expansive.
Organizations and security professionals should address this vulnerability through immediate remediation efforts focusing on implementing proper SSL/TLS certificate validation mechanisms. The recommended mitigations include enforcing strict certificate pinning, implementing robust certificate validation routines that verify certificate chains against trusted authorities, and ensuring proper handling of certificate expiration and revocation checks. This vulnerability highlights the importance of following industry best practices such as those outlined in the OWASP Mobile Security Project and aligns with ATT&CK technique T1046, which covers network service scanning that can be leveraged to identify and exploit such certificate validation weaknesses. Additionally, implementing certificate transparency mechanisms and regular security audits of mobile applications can help prevent similar vulnerabilities from emerging in future releases.
