CVE-2014-7793 in CB - Calciatori Brutti
Summary
by MITRE
The CB - Calciatori Brutti (aka com.calciatori.brutti) application 1.0 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-2014-7793 affects the CB - Calciatori Brutti Android application version 1.0, representing a critical security flaw in the application's implementation of secure communication protocols. This issue stems from the application's failure to properly validate X.509 certificates during SSL/TLS connections, creating a significant attack surface that compromises the integrity of data transmission between the mobile application and remote servers. The flaw directly impacts the application's ability to establish trust with legitimate servers while simultaneously enabling malicious actors to exploit the communication channel through sophisticated man-in-the-middle attacks.
The technical implementation error manifests in the application's SSL certificate validation mechanism, which operates outside the established security protocols designed to protect against certificate forgery and unauthorized server impersonation. This weakness allows attackers to generate or obtain fraudulent certificates that can successfully authenticate with the vulnerable application, effectively bypassing the cryptographic security measures intended to protect sensitive data exchanges. The vulnerability specifically affects the certificate verification process during SSL handshakes, where the application fails to perform proper certificate chain validation, issuer verification, or hostname matching procedures that are fundamental to secure communication.
From an operational perspective, this vulnerability exposes users to significant risk of data interception and theft, as attackers can seamlessly impersonate legitimate servers and capture sensitive information transmitted through the application. The impact extends beyond simple data theft to include potential account compromise, financial fraud, and unauthorized access to personal information, particularly when the application handles user credentials, personal data, or financial transactions. The attack vector requires minimal sophistication, as the vulnerability can be exploited by attackers with basic knowledge of SSL/TLS protocols and certificate manipulation techniques, making it particularly dangerous in environments where users may be unaware of the security risks they face.
The vulnerability aligns with CWE-295, which specifically addresses improper certificate validation in secure communication implementations, and demonstrates clear implications under the ATT&CK framework's T1041 technique for data encryption for exfiltration. Organizations and developers should implement comprehensive certificate pinning mechanisms, ensure proper certificate validation routines, and establish regular security assessments to prevent similar vulnerabilities from emerging in mobile applications. The remediation approach requires the implementation of robust SSL certificate validation including certificate chain verification, hostname validation, and proper error handling for certificate validation failures. Additionally, the application should be updated to enforce strict certificate validation policies that align with industry standards such as those outlined in RFC 5280 for X.509 certificate validation and the OWASP Mobile Security Project recommendations for secure communication in mobile applications.
