CVE-2014-5836 in GittiGidiyor
Summary
by MITRE
The GittiGidiyor (aka com.gittigidiyormobil) application 1.4.1 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-2014-5836 represents a critical security flaw in the GittiGidiyor mobile application version 1.4.1 for Android platforms. This issue stems from the application's failure to properly validate X.509 certificates during SSL/TLS communications, creating a significant attack surface that malicious actors can exploit to compromise user data integrity. The vulnerability specifically affects the certificate verification process within the application's secure communication layer, fundamentally undermining the cryptographic protection mechanisms designed to establish trust between the mobile client and remote servers.
The technical flaw manifests as a missing certificate validation routine that should normally verify the authenticity and legitimacy of SSL certificates presented by remote servers. In proper SSL/TLS implementations, applications must validate certificate chains against trusted Certificate Authorities and ensure that certificates match the expected hostnames through Subject Alternative Name (SAN) or Common Name (CN) fields. The GittiGidiyor application bypasses these essential validation steps, allowing attackers to present fraudulent certificates that appear legitimate to the application. This weakness directly corresponds to CWE-295, which specifically addresses improper certificate validation in security protocols, and aligns with ATT&CK technique T1041 where adversaries manipulate network communications to intercept and manipulate data flows.
The operational impact of this vulnerability extends beyond simple data interception, as it enables comprehensive man-in-the-middle attacks that can compromise user credentials, personal information, financial data, and other sensitive details transmitted through the application. Attackers can exploit this weakness to create fake server endpoints that appear authentic to the application, potentially capturing login credentials, payment information, or private communications. The vulnerability affects all users of the affected application version and persists regardless of the network environment or security measures implemented at the device level, making it particularly dangerous in public Wi-Fi environments or compromised network infrastructures.
Mitigation strategies for CVE-2014-5836 require immediate remediation through application updates that implement proper certificate validation mechanisms. Organizations should ensure that all SSL/TLS certificate verification processes include chain validation against trusted root certificates, hostname matching verification, and implementation of certificate pinning techniques where appropriate. The fix should incorporate standard security libraries and frameworks that properly handle certificate validation according to RFC 5280 standards, ensuring that certificate chains are validated through established trust anchors and that certificate properties match expected values. Additionally, security teams should conduct comprehensive code reviews to identify similar certificate validation issues in other applications and implement automated testing procedures to verify proper SSL certificate handling in future releases, aligning with industry best practices outlined in OWASP Mobile Top 10 and NIST SP 800-52 guidelines for mobile application security.
