CVE-2014-7728 in Logan Banner
Summary
by MITRE
The Logan Banner (aka com.soln.S8B5C1F53B8CBE06D5DE0A0E7E23DCDA7) application 1.0010.b0010 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-2014-7728 affects the Logan Banner Android application version 1.0010.b0010 which implements insecure SSL/TLS certificate verification mechanisms. This represents a critical security flaw that fundamentally undermines the application's ability to establish secure communications with remote servers. The application fails to properly validate X.509 certificates presented by SSL servers, creating a pathway for malicious actors to perform man-in-the-middle attacks against unsuspecting users. This vulnerability directly violates fundamental security principles of secure communication and authentication.
The technical flaw manifests in the application's failure to implement proper certificate pinning or validation procedures during SSL handshakes. When the application establishes connections to remote servers, it does not verify the authenticity of the server certificates against trusted certificate authorities or maintain a list of approved certificates. This allows attackers to generate and present fraudulent certificates that the application will accept as legitimate, effectively bypassing the entire SSL/TLS security framework. The vulnerability stems from inadequate implementation of the certificate validation process, which should normally include checking certificate signatures, expiration dates, and chain of trust.
The operational impact of this vulnerability is severe and multifaceted. Attackers can exploit this weakness to intercept and modify communications between the Android application and its backend services, potentially accessing sensitive user data, authentication credentials, or proprietary information. The vulnerability enables passive eavesdropping capabilities where adversaries can monitor all network traffic without detection, as well as active attack vectors that allow for data manipulation and injection. Users of the application face significant risks including identity theft, financial fraud, and unauthorized access to their accounts or personal information, making this a critical concern for any organization relying on the application for sensitive operations.
Security professionals should implement immediate mitigations including updating the application to version 1.0010.b0011 or later which contains proper certificate verification mechanisms, implementing certificate pinning to restrict connections to specific trusted certificates, and conducting thorough security audits of all network communications. Organizations should also consider deploying network monitoring tools to detect potential man-in-the-middle attacks and establish proper certificate management procedures. This vulnerability aligns with CWE-295 which addresses improper certificate validation and relates to ATT&CK technique T1566 which covers phishing and credential theft through network manipulation. The remediation approach should follow industry best practices for mobile application security, including implementing proper SSL/TLS certificate validation, maintaining updated certificate authorities, and establishing secure coding practices for network communication components.
