CVE-2016-2268 in SecureWorks App
Summary
by MITRE
Dell SecureWorks app before 2.1 for iOS does not validate SSL certificates, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The vulnerability identified as CVE-2016-2268 affects the Dell SecureWorks mobile application version 2.1 and earlier for iOS devices. This security flaw represents a critical weakness in the application's cryptographic implementation that fundamentally undermines the integrity of secure communications between the mobile client and backend servers. The issue stems from the application's failure to properly validate SSL/TLS certificates during the connection establishment process, creating a significant attack surface that malicious actors can exploit to compromise user data and system security.
The technical root cause of this vulnerability lies in the application's improper handling of certificate validation mechanisms within its secure communication framework. When the iOS application attempts to establish encrypted connections with Dell SecureWorks servers, it fails to perform essential certificate verification steps that should confirm the authenticity and trustworthiness of the server's digital certificate. This flaw directly violates established security protocols and standards, as the application essentially accepts any certificate presented by a malicious server without proper validation. The vulnerability aligns with CWE-295, which specifically addresses improper certificate validation in security protocols, and represents a classic example of weak cryptographic practices that leave systems exposed to man-in-the-middle attacks.
The operational impact of this vulnerability extends beyond simple data interception, creating a comprehensive security risk that affects all users of the affected Dell SecureWorks application. Attackers can exploit this weakness by presenting forged SSL certificates to unsuspecting users, effectively allowing them to impersonate legitimate Dell SecureWorks servers and establish fraudulent secure connections. This capability enables attackers to eavesdrop on communications, capture sensitive information transmitted through the application, and potentially manipulate data in transit. The implications are particularly severe given that Dell SecureWorks applications typically handle security-related data, including network monitoring information, threat intelligence, and potentially sensitive corporate security configurations that could be valuable to adversaries.
The attack vector for this vulnerability follows standard man-in-the-middle exploitation patterns where an attacker positions themselves between the vulnerable iOS application and its intended server. Through techniques such as DNS spoofing, ARP cache poisoning, or network interception, the malicious actor can present a crafted certificate that appears legitimate to the unvalidated application. This attack scenario is consistent with ATT&CK technique T1041, which covers data compression and encryption techniques used by adversaries to maintain persistence and avoid detection. The vulnerability essentially removes the cryptographic protection that should prevent such attacks, leaving users exposed to various forms of data compromise including credential theft, configuration data exfiltration, and potential system compromise through the interception of security-related communications.
Organizations and users affected by this vulnerability should immediately update to Dell SecureWorks app version 2.1 or later, which implements proper SSL certificate validation mechanisms. System administrators should also consider implementing additional network monitoring and intrusion detection measures to identify potential exploitation attempts. The remediation process should include comprehensive security awareness training for users to recognize potential signs of man-in-the-middle attacks and ensure proper certificate verification practices. Security teams should conduct thorough vulnerability assessments of other mobile applications within their environment to identify similar certificate validation weaknesses that could expose the organization to similar risks. This vulnerability serves as a critical reminder of the importance of proper cryptographic implementation and the necessity of robust certificate validation processes in mobile security applications, particularly those handling sensitive security-related data.
