CVE-2014-5699 in Parallel Kingdom MMO
Summary
by MITRE
The Parallel Kingdom MMO (aka com.silvermoon.client) application @7F070019 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-2014-5699 affects the Parallel Kingdom MMO Android application, specifically targeting its secure communication protocols. This issue resides within the application's implementation of SSL/TLS certificate validation mechanisms, creating a critical security gap that undermines the integrity of encrypted communications between the mobile client and remote servers. The application's failure to properly validate X.509 certificates represents a fundamental flaw in its cryptographic security architecture, making it susceptible to various forms of network-based attacks that compromise user data and system integrity.
The technical flaw manifests in the application's inability to perform proper certificate chain validation and trust verification processes. When establishing secure connections to SSL servers, the application accepts any certificate presented without verifying its authenticity through established certificate authorities or checking for proper certificate signatures and validity periods. This weakness aligns with CWE-295, which specifically addresses improper certificate validation in security protocols. The vulnerability creates a pathway for attackers to conduct man-in-the-middle attacks by presenting forged certificates that appear legitimate to the vulnerable application, effectively bypassing the intended security protections of SSL/TLS encryption.
The operational impact of this vulnerability extends beyond simple data interception, as it allows attackers to obtain sensitive information through crafted malicious certificates. Mobile gamers using the Parallel Kingdom application become vulnerable to credential theft, session hijacking, and data exfiltration attacks that could compromise personal information, in-game assets, and potentially financial data if the application handles payment transactions. The vulnerability affects all users of the affected Android application version, creating a widespread security risk that undermines trust in the application's security posture and potentially exposes users to identity theft and financial fraud.
Mitigation strategies for this vulnerability require immediate implementation of proper certificate validation mechanisms within the application. Developers should implement robust certificate pinning techniques, establish trust with specific certificate authorities, and configure the application to reject self-signed certificates or certificates from untrusted sources. The solution aligns with ATT&CK technique T1552.001, which addresses credential access through the exploitation of weak cryptographic implementations. Organizations should also consider implementing network monitoring solutions to detect potential man-in-the-middle attacks and establish secure communication channels through proper SSL/TLS configuration. Additionally, users should be advised to avoid using the vulnerable application until patches are deployed and to ensure their devices maintain up-to-date security configurations to minimize exposure to potential attacks targeting this specific vulnerability.
