CVE-2014-7610 in KKMobileApp
Summary
by MITRE
The Kadinlar Kulubu KKMobileApp (aka com.tapatalk.kadinlarkulubucom) application 3.4.3 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-2014-7610 resides within the Kadinlar Kulubu KKMobileApp version 3.4.3 for Android operating systems, representing a critical security flaw that undermines the application's ability to establish secure communications with remote servers. This particular implementation weakness falls under the category of improper certificate validation, where the mobile application fails to properly verify the authenticity of X.509 certificates presented by SSL servers during the secure communication handshake process. The absence of certificate verification creates a significant attack vector that allows malicious actors to perform man-in-the-middle attacks by presenting fraudulent certificates that appear legitimate to the vulnerable application.
The technical flaw manifests in the application's failure to implement proper certificate pinning or validation mechanisms that would normally ensure the authenticity of SSL certificates. When an Android application establishes a secure connection to a server, it typically verifies that the server's certificate is issued by a trusted certificate authority and that the certificate has not been tampered with or forged. However, the KKMobileApp application bypasses this crucial verification step, allowing attackers to intercept communications and present crafted certificates that the application accepts without question. This vulnerability directly violates the fundamental security principle of certificate-based authentication and exposes users to potential data breaches and privacy violations.
The operational impact of this vulnerability extends beyond simple data interception, as it creates opportunities for attackers to gain unauthorized access to sensitive user information that the application may be transmitting or receiving. Mobile applications that fail to validate SSL certificates become particularly vulnerable when handling personal data, login credentials, financial information, or other confidential content that users expect to be protected during transmission. The man-in-the-middle attack scenario enables adversaries to not only eavesdrop on communications but potentially modify data in transit, redirect users to malicious websites, or inject harmful content into the application's data streams. This vulnerability affects the confidentiality, integrity, and availability of data flowing between the mobile application and its backend services.
Security professionals should recognize this issue as a variant of CWE-295, which specifically addresses "Improper Certificate Validation," and aligns with ATT&CK technique T1041, which covers "Exfiltration Over C2 Channel." The vulnerability represents a failure in the application's security architecture that violates industry best practices for mobile application security and certificate validation. Organizations should implement immediate mitigations including updating the application to properly validate SSL certificates, implementing certificate pinning mechanisms, and conducting comprehensive security reviews of all mobile applications to identify similar validation flaws. The remediation process requires developers to ensure that all SSL/TLS connections properly verify certificate chains and implement appropriate security controls to prevent such vulnerabilities from occurring in future releases.
