CVE-2014-7378 in Jobranco
Summary
by MITRE
The Jobranco (aka com.jobranco) 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 CVE-2014-7378 vulnerability affects the Jobranco Android application version 1.1, exposing a critical security flaw in the application's SSL/TLS certificate verification mechanism. This vulnerability represents a fundamental failure in the application's cryptographic security implementation, creating a pathway for sophisticated man-in-the-middle attacks that can compromise user data and system integrity. The flaw specifically targets the application's inability to properly validate X.509 certificates presented by SSL servers during secure communication sessions.
This vulnerability stems from improper certificate validation practices within the application's network security layer, allowing attackers to present fraudulent certificates that appear legitimate to the client application. The absence of certificate pinning or proper certificate chain validation means that the application accepts any certificate presented by a server, regardless of its authenticity or trustworthiness. This weakness directly violates established security principles for secure communications and creates an environment where attackers can intercept, modify, or steal sensitive information transmitted between the mobile application and backend servers.
The operational impact of this vulnerability is severe, as it enables attackers to establish fraudulent secure connections with the application, potentially gaining access to user credentials, personal information, financial data, or other sensitive content. The vulnerability affects the confidentiality and integrity of communications, as attackers can not only eavesdrop on data transfers but also inject malicious content into the communication stream. This represents a significant risk to user privacy and data protection, particularly when the application handles sensitive transactions or personal information, and aligns with attack patterns documented in the mitre ATT&CK framework under the T1041 technique for data encryption for exfiltration.
From a technical perspective, this vulnerability maps directly to CWE-295, which specifically addresses "Improper Certificate Validation," and demonstrates the critical importance of implementing proper SSL/TLS certificate verification in mobile applications. The flaw exemplifies weak cryptographic implementation practices that have been consistently identified as a leading cause of mobile security breaches. Organizations should implement certificate pinning mechanisms, enforce strict certificate validation procedures, and regularly audit their mobile application security configurations. The vulnerability also underscores the necessity of following industry standards such as those outlined in the OWASP Mobile Security Project, particularly the M3 principle regarding secure communication and the importance of proper certificate handling in mobile environments. Effective mitigations include implementing certificate pinning, validating certificate chains against trusted root authorities, and deploying runtime application self-protection mechanisms that can detect and prevent certificate manipulation attempts.
