CVE-2014-6661 in netease movie
Summary
by MITRE
The netease movie (aka com.netease.movie) application 4.7.2 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-2014-6661 affects the netease movie application version 4.7.2 for Android platforms, 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 directly impacts the application's ability to establish trust with remote servers, fundamentally undermining the security model designed to protect sensitive information transmitted between the mobile device and backend services.
The technical flaw manifests as a missing certificate validation mechanism within the application's SSL implementation, specifically failing to perform proper X.509 certificate verification during secure socket connections. This weakness allows attackers to intercept communications between the mobile application and its servers by presenting fraudulent certificates that appear legitimate to the unverified client. The vulnerability falls under CWE-295, which specifically addresses "Improper Certificate Validation," and represents a classic man-in-the-middle attack vector where malicious actors can establish fraudulent connections with the application, potentially capturing user credentials, personal information, or other sensitive data transmitted through the insecure channel. The absence of certificate pinning or proper trust validation creates an environment where attackers can successfully impersonate legitimate servers without detection by the mobile application.
The operational impact of this vulnerability extends beyond simple data interception, as it enables attackers to manipulate the application's communication flow and potentially inject malicious content into the data stream. Users of the netease movie application face risks including credential theft, session hijacking, data corruption, and unauthorized access to their personal information stored within or transmitted by the application. The vulnerability affects all users of the specific application version and persists across all network conditions where SSL/TLS connections are established, making it particularly dangerous as it operates silently without user awareness. This flaw represents a fundamental breakdown in the application's security architecture and could potentially allow attackers to escalate privileges or gain unauthorized access to backend systems through the compromised client.
Mitigation strategies for this vulnerability require immediate implementation of proper SSL certificate validation mechanisms within the application's network communication layer. Security measures should include implementing certificate pinning to ensure only trusted certificates are accepted, configuring proper certificate validation routines that verify certificate chains against trusted root authorities, and establishing robust error handling for SSL connection failures. Organizations should also consider implementing network monitoring to detect unusual traffic patterns that might indicate man-in-the-middle activity and deploy regular security audits to identify similar validation gaps in other applications. The remediation process should align with industry standards such as those outlined in the OWASP Mobile Security Project and should incorporate principles from the ATT&CK framework, specifically targeting the Mitigation and Defense Evasion techniques that attackers might employ when exploiting such certificate validation flaws. Updates to the application must include comprehensive testing of the SSL implementation to ensure proper certificate validation occurs across all supported Android versions and network configurations to prevent similar vulnerabilities from emerging in future releases.
