CVE-2014-6636 in LG Telepresence
Summary
by MITRE
The LG Telepresence (aka com.rsupport.rtc.lge) application 2.0.12 Build 63 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.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified as CVE-2014-6636 affects the LG Telepresence application version 2.0.12 Build 63 running on Android devices. This application, designed for video conferencing and remote collaboration, implements a critical security flaw in its secure communication protocols that undermines the integrity of encrypted connections. The vulnerability resides in the application's failure to properly validate X.509 certificates during SSL/TLS handshakes, creating a significant attack surface that malicious actors can exploit to compromise the confidentiality and integrity of communications.
This security weakness represents a fundamental breakdown in the application's cryptographic implementation, specifically within the certificate validation mechanism that should ensure the authenticity of SSL servers. The flaw allows attackers to perform man-in-the-middle attacks by presenting forged certificates that appear legitimate to the vulnerable application. This failure directly violates industry standards and best practices for secure communication, as outlined in the CWE taxonomy under CWE-295 which addresses improper certificate validation. The vulnerability is particularly concerning because it affects a telepresence application that likely handles sensitive business communications, video conferencing data, and potentially confidential corporate information.
The operational impact of this vulnerability extends beyond simple data interception, as it enables attackers to establish false trust relationships with the application. An attacker positioned between the telepresence device and the server can seamlessly redirect communications to their own malicious server while maintaining the appearance of legitimate connectivity. This capability allows for comprehensive surveillance of video conferences, interception of sensitive meeting data, and potential compromise of business-critical communications. The attack vector is particularly dangerous in enterprise environments where telepresence systems are used for executive meetings, strategic planning sessions, and confidential business discussions. According to ATT&CK framework, this vulnerability maps to T1041 (Exfiltration Over C2 Channel) and T1566 (Phishing) as attackers can leverage this weakness to establish persistent surveillance capabilities.
Mitigation strategies for this vulnerability require immediate attention from system administrators and security teams responsible for deploying and maintaining telepresence systems. The most effective immediate solution involves updating the application to a version that properly implements certificate validation and X.509 certificate verification. Organizations should implement network-level controls including certificate pinning mechanisms, network segmentation, and monitoring for unusual SSL connection patterns. Additionally, security teams should conduct comprehensive vulnerability assessments of all telepresence and video conferencing systems within their environments, particularly focusing on the certificate validation implementations of mobile applications. The remediation process should also include implementing network monitoring solutions capable of detecting anomalous SSL certificate usage patterns and establishing secure communication protocols that enforce proper certificate validation before establishing any encrypted connections. Regular security audits and penetration testing should be conducted to ensure that similar vulnerabilities do not exist in other communication applications within the enterprise infrastructure.
