CVE-2014-5886 in iVysilani ceske televize
Summary
by MITRE
The iVysilani ceske televize (aka cz.motion.ivysilani) application 1.6 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-2014-5886 vulnerability affects the iVysilani ceske televize Android application version 1.6, representing a critical security flaw in the application's SSL certificate verification mechanism. This vulnerability falls under the category of weak cryptographic practices and improper certificate validation, which directly compromises the security of data transmission between the mobile application and remote servers. The application fails to properly validate X.509 certificates presented by SSL servers, creating a dangerous security gap that exposes users to potential man-in-the-middle attacks. This flaw is particularly concerning given that the application likely handles sensitive user data and streaming content that requires secure communication channels.
The technical implementation of this vulnerability stems from the application's failure to perform proper certificate chain validation and trust verification during SSL/TLS connections. When an Android application establishes a secure connection to a server, it should validate the server's SSL certificate against a trusted certificate authority and ensure that the certificate matches the expected hostname. The iVysilani application bypasses these critical validation steps, allowing attackers to present fraudulent certificates that appear legitimate to the application. This weakness can be exploited through various attack vectors including proxy servers, compromised networks, or DNS hijacking techniques that enable attackers to intercept and modify traffic between the application and its servers.
From an operational perspective, this vulnerability creates significant risks for both end users and the application developers. Users may unknowingly transmit sensitive information to attacker-controlled servers, potentially exposing personal data, login credentials, or other confidential information. The impact extends beyond simple data interception to include potential service disruption, content manipulation, and credential theft. Attackers can exploit this vulnerability to redirect users to malicious servers, inject harmful content, or establish persistent surveillance capabilities. The vulnerability also undermines user trust in the application and the broader brand, as users may lose confidence in the security of their data transmission.
The security implications of CVE-2014-5886 align with several cybersecurity frameworks and threat models, particularly those addressing certificate validation failures and secure communication protocols. This vulnerability corresponds to CWE-295, which specifically addresses "Improper Certificate Validation," and represents a clear violation of secure coding practices recommended by OWASP and NIST guidelines. The attack surface for this vulnerability follows patterns consistent with ATT&CK technique T1041, which involves data compression and encryption to avoid detection. Organizations should implement comprehensive security measures including certificate pinning, proper SSL/TLS configuration, and regular security audits to prevent such vulnerabilities from compromising application security. The remediation process requires updating the application to implement proper certificate validation, including hostname verification and certificate chain checking, while also considering the implementation of additional security controls such as certificate transparency monitoring and secure key management practices.
