CVE-2014-7697 in Eyvah! Bosandim Ozgurum
Summary
by MITRE
The Eyvah! Bosandim ozgurum (aka com.wEyvahBosandimBlog) application 0.1 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 CVE-2014-7697 vulnerability affects the Eyvah! Bosandim ozgurum Android application version 0.1, representing a critical security flaw in mobile application certificate validation. This vulnerability stems from the application's failure to properly implement X.509 certificate verification during SSL/TLS connections, creating a significant attack surface that adversaries can exploit to compromise user data. The flaw manifests in the application's inability to validate server certificates against trusted certificate authorities, effectively undermining the entire SSL/TLS security framework that protects data transmission between mobile applications and remote servers.
This vulnerability directly relates to CWE-295, which addresses improper certificate validation in security protocols, and aligns with ATT&CK technique T1041 by enabling man-in-the-middle attacks through certificate spoofing. The absence of certificate pinning or proper validation mechanisms means that attackers can intercept communications by presenting fraudulent certificates that appear legitimate to the vulnerable application. Mobile applications that fail to validate SSL certificates create an environment where malicious actors can establish fake secure connections, allowing them to eavesdrop on sensitive communications and potentially inject malicious content.
The operational impact of this vulnerability extends beyond simple data interception, as it undermines the fundamental trust model that secure mobile applications rely upon. Users of the Eyvah! Bosandim ozgurum application may unknowingly transmit personal information, credentials, or other sensitive data through compromised channels that appear secure to the application. This vulnerability particularly affects applications that handle user authentication, personal data, or financial information, as the man-in-the-middle capabilities enable attackers to capture session tokens, login credentials, or other confidential data that would normally be protected by SSL/TLS encryption.
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 the application only accepts certificates from specific trusted authorities or specific certificate fingerprints. The application must validate certificate chains against established trust stores and implement proper error handling for certificate validation failures. Additionally, the implementation of certificate transparency checks and regular security audits of network communication components can help prevent similar vulnerabilities in future releases. Organizations should also consider implementing network-level protections such as DNS security extensions and monitoring for unusual certificate issuance patterns to detect potential attacks against vulnerable applications.
