CVE-2014-7082 in No Disturb
Summary
by MITRE
The No Disturb (aka com.blogspot.imapp.imnodisturb) application 3.3 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-2014-7082 affects the No Disturb application version 3.3 for Android devices, representing a critical security flaw in certificate validation mechanisms. This application, designed to manage notification settings and system behavior, fails to properly validate X.509 certificates when establishing secure connections with SSL servers. The absence of proper certificate verification creates a significant attack surface that enables malicious actors to conduct man-in-the-middle attacks against users of this application. The flaw stems from the application's failure to implement proper certificate chain validation, hostname verification, or trust store management that are fundamental requirements for secure communication protocols.
This vulnerability directly relates to CWE-295, which addresses improper certificate validation in security protocols, and aligns with ATT&CK technique T1041 by enabling adversaries to intercept and manipulate network traffic. The technical implementation flaw occurs at the SSL/TLS handshake phase where the application accepts any certificate presented by a server without verifying its authenticity through established certificate authorities. Attackers can exploit this weakness by presenting a maliciously crafted certificate that appears to be from a legitimate server, thereby deceiving the application into establishing a secure connection with the attacker's system instead of the intended server. The vulnerability affects the integrity and confidentiality of data transmitted through the application, as the lack of certificate verification means that sensitive information can be intercepted, modified, or exfiltrated without detection.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete compromise of user privacy and system security. Users who rely on the No Disturb application for managing their device notifications and system behavior may unknowingly expose their personal information, including login credentials, communication data, and other sensitive details that the application might process or transmit. The vulnerability is particularly concerning because it affects an application that operates in the background and may have elevated privileges or access to system resources. Attackers can leverage this flaw to establish persistent surveillance capabilities, redirect users to malicious websites, or manipulate the application's intended functionality to serve malicious purposes. The vulnerability also undermines user trust in the application and the broader Android ecosystem, as it demonstrates a fundamental failure in implementing basic security practices.
Mitigation strategies for this vulnerability require immediate attention through proper certificate validation implementation. Organizations and developers should ensure that all SSL/TLS connections implement proper certificate chain validation by verifying certificate signatures against trusted root certificates, performing hostname verification, and maintaining up-to-date trust stores. The application should be updated to include proper certificate pinning mechanisms where appropriate, and all network communications should validate certificates against established certificate authorities. Security patches should address the root cause by implementing standard secure communication protocols that comply with industry best practices and standards such as those defined in NIST SP 800-52 for certificate management. Additionally, users should be advised to avoid using the vulnerable application until proper security updates are implemented, and network administrators should monitor for suspicious certificate usage patterns that might indicate exploitation attempts.
