CVE-2014-5589 in Now Browser (Material)
Summary
by MITRE
The Now Browser (Material) (aka com.browser.nowbasic) 2.8.1 application Material 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-2014-5589 affects the Now Browser Material application version 2.8.1 for Android devices, representing a critical security flaw in the application's implementation of secure communication protocols. This issue stems from the application's failure to properly validate X.509 certificates during SSL/TLS connections, creating a significant attack surface that adversaries can exploit to compromise user data integrity and confidentiality. The vulnerability specifically impacts the browser's certificate verification process, which is fundamental to establishing trust in secure communications between client and server.
This technical flaw constitutes a failure in the application's cryptographic implementation and certificate validation mechanisms, placing the software in violation of standard security practices for secure web browsing. The absence of proper certificate verification allows attackers to perform man-in-the-middle attacks by presenting fraudulent certificates that appear legitimate to the vulnerable application. This weakness directly relates to CWE-295, which addresses improper certificate validation, and represents a failure in the application's trust model that undermines the entire SSL/TLS security framework. The vulnerability enables attackers to intercept and potentially modify communications between users and web servers without detection, as the application accepts any certificate presented without proper validation checks.
The operational impact of this vulnerability extends beyond simple data interception, as it fundamentally compromises the security assurances that users expect when browsing the internet securely. Attackers can exploit this weakness to steal sensitive information including login credentials, personal data, financial information, and other confidential communications transmitted through the vulnerable browser. The implications are particularly severe for mobile users who may access sensitive services while connected to public networks or untrusted Wi-Fi networks, where such attacks are more commonly executed. This vulnerability affects all users of the specific application version and creates persistent security risks until properly addressed through either application updates or user awareness of the risks involved.
Mitigation strategies for this vulnerability require immediate action from both application developers and end users. Application developers must implement proper certificate validation mechanisms that comply with industry standards such as those specified in the TLS protocol specifications and PKI best practices. The fix should include robust certificate chain validation, proper hostname verification, and implementation of certificate pinning where appropriate. Users should be advised to avoid using this vulnerable application for accessing sensitive websites or performing transactions, particularly on untrusted networks. Organizations should consider implementing network monitoring solutions to detect potential man-in-the-middle attacks and ensure that all mobile applications undergo thorough security testing before deployment. This vulnerability also highlights the importance of regular security audits and updates in mobile application development, as outlined in the ATT&CK framework's mobile application security considerations, where such failures can lead to significant data breaches and user privacy violations.
