CVE-2014-6726 in 30A
Summary
by MITRE
The 30A (aka com.app30a) application 5.26.2 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-2014-6726 resides within the 30A Android application version 5.26.2, specifically targeting the application's handling of SSL/TLS certificate verification mechanisms. This weakness represents a critical security flaw in the application's cryptographic implementation, where the software fails to properly validate X.509 certificates presented by SSL servers during secure communications. The absence of certificate verification creates a significant attack surface that adversaries can exploit to conduct man-in-the-middle attacks against users of the application. This vulnerability directly impacts the fundamental security assurances that SSL/TLS protocols are designed to provide, including authentication and data integrity protection.
The technical flaw manifests as a failure in the certificate validation process where the application accepts any certificate presented by a server without performing the necessary cryptographic checks. This includes verification of certificate chains, expiration dates, and proper signing authorities. The vulnerability stems from improper implementation of SSL/TLS certificate validation routines, which is classified under CWE-295 as "Improper Certificate Validation." Attackers can leverage this weakness by presenting a maliciously crafted certificate that appears to be from a legitimate server, thereby fooling the application into establishing a secure connection with the attacker's server instead of the intended legitimate service. This allows for the interception and potential manipulation of all data transmitted between the user and the server.
The operational impact of this vulnerability extends beyond simple data theft, as it compromises the entire security model of the application. Users of the 30A application become vulnerable to various attack vectors including credential theft, session hijacking, and sensitive data interception. The vulnerability affects all communications that rely on SSL/TLS encryption within the application, potentially exposing user credentials, personal information, and business data. From an adversarial perspective, this weakness aligns with ATT&CK technique T1566.001 for "Phishing: Spearphishing Attachment" and T1041 for "Exfiltration Over C2 Channel" as attackers can establish persistent surveillance and data collection capabilities through the compromised communication channels. The vulnerability essentially renders the application's security layer ineffective, making it a prime target for attackers seeking to exploit user trust in the application's secure communication features.
Mitigation strategies for this vulnerability require immediate implementation of proper certificate validation mechanisms within the application. The fix involves implementing robust certificate chain validation, including verification of certificate signatures, proper certificate authority trust, and expiration date checks. Organizations should implement certificate pinning techniques where the application pre-loads trusted certificate fingerprints and validates that the server presents certificates matching these pinned values. Additionally, the application should be updated to use modern SSL/TLS protocol versions and cipher suites that provide adequate security guarantees. Security patches should include comprehensive certificate validation routines that follow industry standards such as those defined in RFC 5280 for X.509 certificate handling and RFC 5246 for TLS protocol implementation. The remediation process must also include thorough testing of the certificate validation logic to ensure that legitimate server certificates are accepted while malicious certificates are properly rejected, thereby restoring the intended security posture of the application's secure communication infrastructure.
