CVE-2014-7029 in Bultmonster Registret
Summary
by MITRE
The Bultmonster Registret (aka com.bultmonster.registret) application 1.1 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-2014-7029 affects the Bultmonster Registret Android application version 1.1, presenting a critical security flaw in the application's SSL/TLS certificate validation mechanism. This weakness resides in the application's failure to properly implement X.509 certificate verification during secure communications, creating a significant attack surface that adversaries can exploit to compromise user data integrity and confidentiality.
The technical flaw manifests as a complete absence of SSL certificate validation within the application's network communication stack. When the application establishes connections to remote servers using HTTPS or SSL protocols, it fails to validate the server certificates against trusted certificate authorities or perform proper certificate chain verification. This vulnerability directly maps to CWE-295, which specifically addresses "Improper Certificate Validation," and represents a fundamental breakdown in the application's cryptographic security implementation. The absence of certificate pinning or proper validation means that any certificate presented by a malicious server, regardless of its legitimacy or trustworthiness, will be accepted by the application.
The operational impact of this vulnerability is severe and multifaceted, creating multiple attack vectors for man-in-the-middle adversaries. Attackers can exploit this weakness by intercepting network traffic between the Android application and its servers, presenting forged SSL certificates that appear legitimate to the vulnerable application. This allows attackers to decrypt and modify sensitive information transmitted between the user's device and the application servers, potentially compromising personal data, authentication tokens, or other confidential information. The vulnerability affects the confidentiality and integrity of all data transmitted through the application, making it particularly dangerous for any application handling user credentials, personal information, or financial data.
This security weakness directly aligns with tactics described in the MITRE ATT&CK framework under the T1046 category, which covers "Network Service Scanning' and T1566, 'Phishing', as attackers can leverage this vulnerability to establish fraudulent communication channels. The vulnerability also corresponds to the broader category of credential theft and data interception attacks, where adversaries can use the compromised communication channel to capture authentication information or manipulate application data. Organizations using this application would be vulnerable to attacks targeting their users' sensitive information, with potential consequences including identity theft, financial fraud, and unauthorized access to personal accounts.
The recommended mitigations for this vulnerability involve implementing proper SSL certificate validation mechanisms within the application. Developers should ensure that all SSL/TLS connections perform certificate chain validation against trusted certificate authorities, implement certificate pinning for critical endpoints, and utilize proper certificate validation libraries. The application should verify certificate expiration dates, check certificate subject and issuer information, and ensure that certificates are issued for the specific domain being accessed. Additionally, implementing certificate revocation checking through OCSP or CRL validation would provide further security layers. Organizations should also consider implementing network monitoring to detect anomalous traffic patterns that might indicate certificate manipulation attempts, and conduct regular security assessments to identify similar vulnerabilities in other applications.
