CVE-2014-7606 in Concursive
Summary
by MITRE
The Concursive (aka com.concursive.app) application 2.1 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 Concursive Android application version 2.1 contains a critical security vulnerability that fundamentally undermines the integrity of its secure communication channels. This flaw represents a failure in the application's certificate validation mechanism, specifically within its implementation of SSL/TLS security protocols. The vulnerability exists in the application's handling of X.509 certificates, which are essential components for establishing trust between mobile applications and remote servers. When an application fails to properly validate these certificates, it creates an opening for malicious actors to exploit the communication channel.
The technical nature of this vulnerability stems from the application's complete absence of certificate verification processes during SSL handshakes. This means that when the Concursive application establishes secure connections to its backend servers, it accepts any certificate presented without performing the necessary cryptographic checks that validate the certificate's authenticity and trust chain. The vulnerability allows attackers to perform man-in-the-middle attacks by presenting forged certificates that appear legitimate to the application. This weakness directly violates fundamental security principles of certificate-based authentication and exposes all data transmitted through the application to potential interception and manipulation.
The operational impact of this vulnerability is severe and multifaceted, affecting both the confidentiality and integrity of user data. Attackers can exploit this flaw to intercept sensitive information transmitted between the mobile application and its servers, potentially accessing personal data, authentication credentials, or business-critical information. The vulnerability is particularly dangerous because it affects the core security infrastructure of the application, making it impossible for users to trust that their communications are secure. This type of vulnerability aligns with CWE-295, which specifically addresses improper certificate validation, and represents a clear violation of the secure communication standards that mobile applications must implement.
From an adversarial perspective, this vulnerability provides attackers with a straightforward path to compromise user sessions and data. The attack vector requires minimal technical expertise since the application's security mechanisms are completely disabled. The vulnerability enables attackers to create fake server identities that the application accepts without question, allowing them to eavesdrop on communications or inject malicious data. This weakness significantly increases the risk profile for organizations using the application, as it essentially removes any protection against active network attacks. The security implications extend beyond individual user data to potentially compromise entire enterprise systems that rely on the application for business operations.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The application developers must implement proper certificate validation mechanisms that verify the certificate's authenticity against trusted certificate authorities and validate the certificate chain through established cryptographic processes. This includes implementing certificate pinning where appropriate and ensuring that all SSL/TLS connections perform proper certificate verification before establishing secure communication. Organizations should also consider implementing network-level monitoring to detect potential man-in-the-middle attacks and establish regular security assessments to identify similar vulnerabilities in their mobile applications. The remediation process should align with industry best practices for mobile application security and adhere to established frameworks such as those defined in the OWASP Mobile Security Project.
