CVE-2014-7584 in ACN2GO
Summary
by MITRE
The ACN2GO (aka com.dataparadigm.acnmobile) application 1.7 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-2014-7584 affects the ACN2GO mobile application version 1.7 for Android operating systems, presenting a critical security flaw in the application's SSL/TLS certificate verification process. This weakness fundamentally undermines the cryptographic security measures designed to establish trust between mobile clients and remote servers, creating a dangerous attack surface that malicious actors can exploit to compromise sensitive data transmission. The vulnerability resides in the application's failure to properly validate X.509 certificates, which are essential components of the public key infrastructure that ensures secure communication channels.
This security deficiency represents a classic implementation flaw in certificate validation mechanisms, classified under CWE-295 which specifically addresses improper certificate validation. The application's inability to verify SSL server certificates creates a man-in-the-middle attack vector where adversaries can intercept communications between the mobile application and backend servers. Attackers can generate and present fraudulent certificates that appear legitimate to the vulnerable application, enabling them to decrypt and access sensitive information transmitted through the compromised communication channel. The flaw essentially disables the certificate pinning and trust verification processes that are fundamental to secure mobile application architecture.
The operational impact of this vulnerability extends beyond simple data interception, as it fundamentally compromises the confidentiality and integrity of all information exchanged between the mobile application and remote servers. Sensitive data including user credentials, personal information, financial details, and proprietary business data could be exposed to unauthorized parties. The vulnerability affects the application's security posture across all network communications, potentially allowing attackers to not only read transmitted data but also to modify it, creating a complete breakdown in the security model that users expect from secure mobile applications. This weakness particularly impacts applications handling sensitive information where data integrity and confidentiality are paramount.
Mitigation strategies for this vulnerability require immediate implementation of proper certificate validation mechanisms within the application. The recommended approach involves implementing strict certificate pinning with certificate or public key validation, ensuring that the application only accepts certificates from trusted Certificate Authorities and validates certificate chains properly. Security professionals should implement certificate validation routines that check certificate expiration dates, verify certificate signatures, and ensure proper certificate chain validation according to industry standards. Organizations should also consider implementing network monitoring and intrusion detection systems to identify potential exploitation attempts. The remediation process must follow established security frameworks and best practices, including regular security testing and validation of certificate handling implementations. Additionally, the application should be updated to include proper error handling for certificate validation failures and implement appropriate logging mechanisms to detect and respond to potential certificate validation issues.
