CVE-2014-5564 in Angry Gran Toss
Summary
by MITRE
The Angry Gran Toss (aka com.aceviral.angrygrantoss) application 1.1.1 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 vulnerability identified as CVE-2014-5564 affects the Angry Gran Toss mobile application version 1.1.1 for Android platforms, representing a critical security flaw in the application's secure communication implementation. This issue stems from the application's failure to properly validate X.509 certificates during SSL/TLS connections, creating a significant attack vector that undermines the fundamental security assurances provided by cryptographic protocols. The flaw specifically manifests in the application's inability to perform certificate chain validation, allowing malicious actors to exploit the trust relationship between client and server.
From a technical perspective, the vulnerability constitutes a certificate verification failure that directly violates established security protocols designed to prevent man-in-the-middle attacks. The application's SSL implementation lacks proper certificate pinning mechanisms and certificate trust validation, enabling attackers to present forged certificates that the application accepts as legitimate. This weakness aligns with CWE-295, which categorizes improper certificate validation as a critical flaw in secure communication implementations. The absence of certificate verification means that the application cannot distinguish between legitimate servers and malicious impostors, creating an environment where sensitive data can be intercepted or manipulated during transmission.
The operational impact of this vulnerability extends beyond simple data interception to encompass potential complete system compromise and data exfiltration. Mobile applications that fail to validate SSL certificates create pathways for attackers to establish unauthorized communication channels, potentially allowing them to access user credentials, personal information, or other sensitive data transmitted through the application's network connections. The vulnerability is particularly concerning in mobile environments where applications often handle sensitive user data and operate in potentially insecure network conditions. This flaw directly maps to ATT&CK technique T1041, which describes data compression and encryption to avoid detection, as the compromised application may be used to exfiltrate data through manipulated SSL connections.
Mitigation strategies for this vulnerability require immediate implementation of proper certificate validation mechanisms within the application's SSL/TLS communication stack. Security experts recommend implementing certificate pinning to ensure that the application only accepts specific certificates or certificate authorities, thereby preventing the acceptance of forged certificates. The application should also incorporate proper certificate chain validation procedures that verify certificate signatures, expiration dates, and trust relationships with recognized certificate authorities. Additionally, developers should implement certificate revocation checking mechanisms to detect and reject compromised certificates. Organizations should also consider implementing network monitoring solutions to detect anomalous SSL traffic patterns that may indicate exploitation attempts. The remediation process must include comprehensive code review and security testing to ensure that all network communication pathways properly validate SSL certificates and maintain the integrity of the application's secure communication infrastructure.
