CVE-2014-7682 in GR8! Tv
Summary
by MITRE
The GR8! TV (aka com.magzter.greighttv) application 3.0 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-2014-7682 resides within the GR8! TV application version 3.0 for Android platforms, representing a critical security flaw in the application's cryptographic implementation. This weakness fundamentally undermines the secure communication channel between the mobile application and remote servers, creating a pathway for sophisticated cyber adversaries to compromise user data integrity and confidentiality. The vulnerability specifically affects the application's SSL/TLS certificate validation mechanisms, which are essential components of modern secure communication protocols designed to establish trust between client and server entities.
The technical flaw manifests in the application's failure to properly validate X.509 certificates during SSL handshakes, a critical security control that should verify the authenticity and legitimacy of server certificates. This absence of certificate verification creates a dangerous trust model where the application accepts any certificate presented by a server, regardless of its validity or authenticity. The vulnerability directly corresponds to CWE-295, which focuses on improper certificate validation, and represents a classic example of weak cryptographic implementation that violates fundamental security principles. Attackers can exploit this weakness by deploying malicious certificates that appear legitimate to the vulnerable application, effectively bypassing the security measures designed to protect sensitive information exchanges.
Operationally, this vulnerability enables man-in-the-middle attacks that can have severe consequences for both individual users and the application's reputation. Adversaries can intercept and modify communications between the GR8! TV application and its backend services, potentially gaining access to user credentials, personal information, and other sensitive data transmitted over the network. The impact extends beyond simple data theft to include potential service disruption, unauthorized access to premium content, and the possibility of injecting malicious payloads into the application's communication channels. This weakness particularly affects applications that handle user authentication, payment information, or private content, as the vulnerability creates a persistent attack surface that remains active as long as the vulnerable application is installed on user devices.
The exploitation of this vulnerability aligns with several tactics described in the MITRE ATT&CK framework, specifically targeting the credential access and defense evasion categories. Attackers can leverage this flaw to establish persistent access points within the application's communication infrastructure, making it difficult to detect and remediate the compromise. Organizations should implement immediate mitigation strategies including certificate pinning mechanisms, regular security audits of mobile applications, and comprehensive vulnerability assessments to identify similar weaknesses in other applications. The recommended remediation approach involves implementing proper X.509 certificate validation procedures, enforcing strict certificate chain verification, and adopting industry best practices for secure mobile application development. Additionally, developers should reference security standards such as NIST SP 800-52 and ISO/IEC 15408 to ensure proper implementation of cryptographic controls and prevent similar vulnerabilities in future application releases.
