The vulnerability identified as CVE-2015-5629 affects the NTT Broadband Platform Japan Connected-free Wi-Fi application across both Android and iOS platforms. This security flaw resides in the application's URL whitelist protection mechanism, which is designed to restrict access to only approved web resources while users connect to the Wi-Fi network. The vulnerability allows malicious actors to circumvent these security controls through unspecified attack vectors that undermine the intended network access restrictions.
The technical implementation of this vulnerability demonstrates a critical flaw in the application's security architecture where the URL whitelist mechanism fails to properly validate or enforce access controls. This weakness creates a pathway for attackers to access unauthorized web resources that should be blocked by the whitelist protection. The unspecified vectors suggest that the vulnerability may stem from inadequate input validation, improper access control implementation, or flawed session management within the application's network filtering logic.
From an operational perspective, this vulnerability poses significant risks to network security and user privacy. Attackers who exploit this weakness can bypass content filtering restrictions and potentially gain access to malicious websites, sensitive corporate resources, or unauthorized services. The impact extends beyond simple bypassing of restrictions, as it may enable man-in-the-middle attacks, data exfiltration, or the delivery of malware through compromised network connections. Organizations relying on this Wi-Fi platform for secure network access are particularly vulnerable to these attacks.
The vulnerability aligns with CWE-284, which addresses improper access control issues, and may also relate to CWE-352, concerning cross-site request forgery, depending on the specific implementation details. From an attack framework perspective, this vulnerability would likely map to ATT&CK technique T1071.004 for application layer protocol: DNS and T1566 for credential harvesting, as attackers could leverage the bypassed access to gather sensitive information or credentials. Organizations should implement immediate mitigations including updating to patched versions of the application, reviewing and strengthening network access controls, and monitoring for suspicious network activity. Additionally, network administrators should consider implementing additional layers of security such as deep packet inspection, network segmentation, and enhanced monitoring of network traffic to detect potential exploitation attempts.
