CVE-2014-5633 in Kiss Kiss Office
Summary
by MITRE
The Kiss Kiss Office (aka com.girlsgames123.kisskissoffice) application 1 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-2014-5633 affects the Kiss Kiss Office Android application version 1, presenting a critical security flaw in the application's approach to SSL certificate validation. This weakness stems from the application's failure to properly verify X.509 certificates presented by SSL servers during secure communications. The absence of certificate verification creates a significant attack surface that enables malicious actors to perform man-in-the-middle attacks against users of the application. The vulnerability specifically impacts the application's secure communication channels, potentially exposing user data and sensitive information transmitted between the mobile device and remote servers.
The technical flaw manifests as a complete absence of SSL certificate validation mechanisms within the application's network communication stack. When the application establishes secure connections to remote servers, it fails to validate the presented SSL certificates against trusted certificate authorities or perform proper certificate chain validation. This omission allows attackers to present fraudulent certificates that appear legitimate to the application, enabling them to intercept, modify, or steal sensitive data transmitted through the application's network connections. The vulnerability directly relates to CWE-295, which addresses improper certificate validation in secure communications, and represents a fundamental failure in the application's security architecture.
The operational impact of this vulnerability is severe and multifaceted, particularly given the nature of the application's functionality as a mobile game platform. Users of the Kiss Kiss Office application face significant risks including unauthorized access to their personal information, account credentials, payment details, and other sensitive data that may be transmitted during application usage. Attackers can exploit this vulnerability to intercept communications, potentially gaining access to user accounts, financial information, or other confidential data. The vulnerability is particularly concerning for applications that handle user authentication, personal data, or financial transactions, as it undermines the fundamental security guarantees that SSL/TLS protocols are designed to provide.
Mitigation strategies for this vulnerability require immediate implementation of proper SSL certificate validation mechanisms within the application. Developers should implement certificate pinning techniques to ensure that only specific certificates or certificate authorities are accepted for secure communications. The application must validate certificate chains against trusted root certificates, check certificate expiration dates, and verify certificate subject names against expected server identities. Additionally, implementing certificate transparency and using secure communication libraries that properly handle certificate validation can significantly reduce the attack surface. Organizations should also consider implementing network monitoring to detect potential man-in-the-middle attacks and establish incident response procedures for addressing such security breaches. This vulnerability aligns with ATT&CK technique T1046 which covers network service scanning and T1566 which addresses credential harvesting through social engineering, though the specific exploitation pathway is through network protocol manipulation rather than traditional social engineering approaches.
