CVE-2014-6777 in blueeleph
Summary
by MITRE
The blueeleph (aka eg.film.blueeleph) application 1.0 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-2014-6777 resides within the blueeleph application version 1.0 for Android operating systems, representing a critical security flaw in the application's implementation of secure communication protocols. 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 assurances that SSL/TLS protocols are designed to provide.
The technical flaw manifests as a complete absence of certificate verification mechanisms within the application's network communication stack. When the blueeleph application attempts to establish secure connections with remote servers, it fails to perform the essential X.509 certificate validation steps that should confirm the server's identity against trusted certificate authorities. This omission allows attackers to present fraudulent certificates that appear legitimate to the application, enabling them to intercept, modify, or steal sensitive data transmitted between the user's device and the targeted servers. The vulnerability specifically affects the SSL/TLS handshake process where certificate validation should occur but does not, creating a pathway for malicious actors to establish fraudulent secure connections.
The operational impact of this vulnerability extends beyond simple data interception to encompass comprehensive man-in-the-middle attack capabilities that can compromise user privacy and security. Attackers can exploit this weakness to perform session hijacking, steal authentication credentials, access personal information, and potentially execute further malicious activities through the compromised application. The vulnerability affects all users of the blueeleph application version 1.0 who engage in network communications, making it a widespread concern for anyone utilizing the application in environments where network security is paramount. The lack of certificate verification essentially renders the application's secure communication layer ineffective, leaving users vulnerable to sophisticated cyber attacks that could result in financial loss, identity theft, or other serious consequences.
Security professionals should recognize this vulnerability as aligning with CWE-295, which specifically addresses "Improper Certificate Validation," and it maps to ATT&CK technique T1041 where adversaries use man-in-the-middle techniques to intercept communications. The recommended mitigations include implementing proper certificate pinning mechanisms, ensuring all SSL/TLS connections validate certificates against trusted authorities, and establishing robust certificate verification processes within the application's network stack. Organizations should also consider immediate remediation efforts including application updates, network monitoring for suspicious activities, and user education about the risks associated with using vulnerable applications. Additionally, the vulnerability demonstrates the critical importance of following secure coding practices and implementing comprehensive security testing protocols to identify and address such fundamental flaws before they can be exploited in real-world scenarios.
