CVE-2014-7313 in One You Fitness
Summary
by MITRE
The One You Fitness (aka com.app_oneyou.layout) application 1.399 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-2014-7313 affects the One You Fitness mobile application version 1.399 for Android devices, representing a critical security flaw in the application's implementation of secure communication protocols. This issue resides within the application's SSL/TLS certificate validation mechanism, where the software fails to properly verify X.509 certificates presented by remote servers during secure connections. The absence of proper certificate verification creates a significant attack surface that adversaries can exploit to compromise the confidentiality and integrity of data transmitted between the mobile application and its backend services.
The technical flaw manifests as a failure in the certificate chain validation process, where the application accepts any certificate presented by a server without performing the necessary cryptographic checks that should confirm the certificate's authenticity and trustworthiness. This vulnerability directly maps to CWE-295, which addresses "Improper Certificate Validation," and represents a fundamental breakdown in the application's secure communication framework. Attackers can leverage this weakness through man-in-the-middle attacks by presenting a maliciously crafted certificate that appears legitimate to the vulnerable application, thereby establishing a false sense of security while actually intercepting and potentially modifying all communications between the mobile device and the server.
The operational impact of this vulnerability extends beyond simple data interception, as it enables attackers to obtain sensitive information that users may transmit through the application. This includes but is not limited to personal health data, user credentials, payment information, and other confidential details that the application may process or store. The vulnerability essentially undermines the entire purpose of implementing SSL/TLS encryption, which is to ensure that communications remain private and that the communicating parties can trust each other's identities. From an attacker's perspective, this weakness provides a straightforward path to compromise user privacy and potentially conduct identity theft or financial fraud, particularly if the application handles sensitive user information or transactions.
The security implications of this vulnerability align with tactics described in the MITRE ATT&CK framework under the "Credential Access" and "Initial Access" domains, where attackers can establish persistent access through compromised communication channels. Organizations should consider implementing network-level mitigations such as certificate pinning to prevent the acceptance of unauthorized certificates, while developers must ensure proper implementation of SSL/TLS certificate validation routines that verify certificate chains against trusted Certificate Authorities. Additionally, the application should be updated to include proper certificate validation logic that checks certificate expiration dates, issuer authenticity, and certificate revocation status to prevent exploitation of this vulnerability.
