CVE-2014-6757 in Koran - AlqoranVideos
Summary
by MITRE
The Koran - AlqoranVideos (aka com.alqoran.videos.example) 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-2014-6757 affects the Koran - AlqoranVideos Android application version 1.0, representing a critical security flaw in the application's implementation of secure communication protocols. This issue resides within the application's network security architecture where it fails to properly validate SSL/TLS certificates presented by remote servers during secure connections. The absence of certificate verification creates a significant attack vector that undermines the fundamental security guarantees of encrypted communications.
The technical flaw manifests as a failure to implement proper certificate chain validation and hostname verification mechanisms. When the application establishes SSL connections to remote servers, it accepts any certificate presented without performing the necessary cryptographic checks that ensure the certificate's authenticity and validity. This includes failing to verify certificate signatures, check certificate expiration dates, validate certificate authorities, and confirm that the certificate's subject matches the target server's hostname. The vulnerability directly maps to CWE-295, which specifically addresses improper certificate validation in secure communications, and represents a classic implementation of the Man-in-the-Middle attack pattern documented in the MITRE ATT&CK framework under T1046 for network service scanning and T1566 for credential access through phishing.
The operational impact of this vulnerability is severe and multifaceted, as it allows attackers to conduct successful man-in-the-middle attacks against users of the application. An attacker positioned between the mobile device and the server can present a fraudulent certificate that appears legitimate to the vulnerable application, enabling them to decrypt and monitor all communications between the user and the server. This capability extends to potentially capturing sensitive user data, session tokens, authentication credentials, and any other information transmitted through the insecure connection. The attack surface is particularly concerning given that the application deals with religious content, suggesting it may handle user personal information, preferences, or potentially financial transactions.
Mitigation strategies for this vulnerability require immediate implementation of proper SSL certificate validation mechanisms within the application. The recommended approach involves implementing certificate pinning, where the application explicitly trusts only specific certificates or certificate authorities rather than accepting any certificate from any authority. Additionally, the application must enforce strict hostname verification to ensure that certificates are only accepted for the intended server domains. Security updates should include proper implementation of certificate chain validation, including signature verification, expiration checking, and revocation status verification through mechanisms such as OCSP or CRL checking. Organizations should also consider implementing network-level monitoring to detect potential man-in-the-middle attacks and establish secure communication protocols that align with industry standards such as those defined in NIST SP 800-52 for certificate management and RFC 5280 for X.509 certificate standards. The fix must be comprehensive and tested thoroughly to ensure that all network communication paths within the application properly validate SSL certificates before establishing secure connections.
