CVE-2014-7677 in Scudetto
Summary
by MITRE
The Scudetto (aka com.scudetto) application 2.7 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-2014-7677 affects the Scudetto mobile application version 2.7 for Android devices, representing a critical security flaw in the application's SSL/TLS certificate validation mechanism. This issue falls under the broader category of insecure communication protocols and demonstrates a fundamental failure in implementing proper certificate verification procedures within mobile applications. The application's failure to validate X.509 certificates from SSL servers creates a significant attack surface that can be exploited by malicious actors to compromise user data and system integrity.
The technical flaw stems from the application's implementation of SSL/TLS connections where it bypasses the standard certificate verification process that should occur during the secure communication establishment. This vulnerability specifically impacts the certificate chain validation process, where the application should verify the certificate's authenticity through trusted certificate authorities but instead accepts any certificate presented by the server. The flaw allows attackers to perform man-in-the-middle attacks by presenting a crafted certificate that appears legitimate to the application, thereby undermining the entire purpose of SSL/TLS encryption. This weakness directly relates to CWE-295 which addresses improper certificate validation and represents a critical failure in the application's cryptographic implementation.
The operational impact of this vulnerability extends beyond simple data interception, as it enables attackers to gain unauthorized access to sensitive user information that may include personal data, financial details, or other confidential information transmitted through the application. Mobile applications that handle user credentials, payment information, or private communications are particularly vulnerable to exploitation. The attack vector requires minimal technical expertise, making it accessible to a wide range of threat actors and potentially leading to widespread data breaches across the application's user base. This vulnerability also aligns with ATT&CK technique T1041 which covers data compression and encryption, as the compromised application fails to properly secure data in transit through inadequate certificate validation.
Mitigation strategies for this vulnerability must focus on implementing proper SSL/TLS certificate validation within the application's networking layer. Developers should ensure that certificate pinning is implemented to validate against specific certificate fingerprints or public keys rather than relying on the default trust store. The application should enforce strict certificate validation that checks certificate expiration dates, verifies the certificate chain against trusted authorities, and implements proper hostname verification. Additionally, security patches should be deployed immediately to update the application's SSL/TLS implementation and ensure that all network communications are properly secured. Organizations should also consider implementing network monitoring to detect potential man-in-the-middle attacks and establish procedures for rapid response to security incidents. The vulnerability highlights the importance of following mobile security best practices and adhering to industry standards such as those outlined in the OWASP Mobile Security Project, which emphasizes the critical need for proper cryptographic implementation in mobile applications.
