CVE-2014-7447 in Dattch - The Lesbian App
Summary
by MITRE
The Dattch - The Lesbian App (aka com.dattch.dattch.app) application 0.30 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-2014-7447 affects the Dattch - The Lesbian App version 0.30 for Android operating systems, representing a critical security flaw in the application's cryptographic implementation. This weakness resides in the application's failure to properly validate X.509 certificates during SSL/TLS connections, creating a significant exposure that undermines the fundamental security assurances typically provided by secure communication protocols. The vulnerability directly impacts the app's ability to establish trust with remote servers, leaving users susceptible to various forms of network-based attacks that compromise data integrity and confidentiality.
The technical flaw manifests as a complete absence of certificate verification mechanisms within the application's SSL implementation, which is classified as a weakness under CWE-295 - Improper Certificate Validation. This particular vulnerability enables attackers to execute successful man-in-the-middle attacks by presenting fraudulent certificates that appear legitimate to the vulnerable application. The application's failure to perform certificate chain validation, hostname verification, or signature validation means that any malicious actor with access to a certificate authority can create a convincing fake certificate that the application will accept without question. This represents a fundamental breakdown in the security architecture that should normally be enforced by the underlying operating system's security framework.
The operational impact of this vulnerability extends beyond simple data interception to encompass complete session hijacking and data manipulation capabilities for attackers. When users connect to servers through the vulnerable application, their communications become susceptible to eavesdropping, data tampering, and authentication bypass attempts. The vulnerability affects all network communications within the application that rely on SSL/TLS encryption, potentially exposing user credentials, personal information, and any data transmitted between the mobile device and remote servers. This creates a persistent threat vector that remains active as long as the vulnerable version of the application is installed and in use, with no mechanism for users to detect or prevent the exploitation.
Mitigation strategies for this vulnerability require immediate remediation through application updates that implement proper certificate validation procedures. Security best practices dictate that all SSL/TLS implementations must perform comprehensive certificate verification including chain of trust validation, hostname matching, and signature verification to prevent the acceptance of fraudulent certificates. Organizations should also consider implementing network-level monitoring to detect potential man-in-the-middle activities and establish secure communication policies that require certificate pinning for sensitive applications. This vulnerability aligns with ATT&CK technique T1041 - Exfiltration Over C2 Channel, as it enables attackers to establish covert communication channels for data theft, and represents a failure in the application's secure coding practices that should be addressed through comprehensive security testing and code review processes. The remediation process must include thorough testing of the certificate validation logic to ensure that all potential attack vectors are properly addressed and that the application maintains proper security posture against cryptographic attacks.
