CVE-2026-35145 in DFXAnalytics
Summary
by MITRE • 07/16/2026
HCL DFXAnalytics is affected by a Missing HTTP Strict-Transport-Security Header vulnerability. The application fails to implement the HTTP Strict Transport Security (HSTS) policy within its responses, which could allow a remote attacker to downgrade the communication channel to an unencrypted connection (HTTP) and conduct man-in-the-middle (MitM) attacks. To remediate this, the application must include the "Strict-Transport-Security" header in all web application responses.

The HCL DFXAnalytics application exhibits a critical security deficiency through its failure to implement the HTTP Strict Transport Security (HSTS) policy, creating a significant vulnerability that directly impacts the confidentiality and integrity of communications between clients and the server. This missing security header represents a fundamental gap in the application's defensive posture, as it fails to establish a mandatory secure communication channel that should be enforced by default. The absence of HSTS allows attackers to exploit the lack of explicit security directives, potentially compromising user sessions and sensitive data exchanges through various attack vectors.
This vulnerability falls under the category of insufficient transport layer protection as defined by CWE-319, specifically manifesting as a failure to implement proper HTTP security headers that are essential for establishing secure communication channels. The missing Strict-Transport-Security header creates an environment where attackers can successfully perform man-in-the-middle attacks by intercepting and modifying traffic between the user's browser and the application server. Without HSTS enforcement, users remain susceptible to protocol downgrade attacks where encrypted HTTPS connections are forcibly redirected to unencrypted HTTP connections, making the entire communication channel vulnerable to eavesdropping and data manipulation.
The operational impact of this vulnerability extends beyond simple data exposure, as it fundamentally undermines the trust model that secure web applications must maintain. Attackers leveraging this weakness can execute session hijacking attempts, steal authentication tokens, and potentially access sensitive business intelligence or proprietary information processed through the DFXAnalytics platform. This vulnerability directly aligns with ATT&CK technique T1566.002 which covers credential access through man-in-the-middle attacks, where the lack of proper transport security creates an ideal environment for such exploitation attempts.
From a mitigation perspective, implementing the Strict-Transport-Security header represents the primary remediation strategy that must be deployed across all application responses to enforce secure communication channels. The header should include appropriate parameters such as max-age directives to specify the duration of HSTS enforcement and includeSubDomains flag to ensure all subdomains inherit the security policy. Additionally, organizations should consider implementing additional security measures including proper certificate management, regular security assessments, and comprehensive network monitoring to detect potential exploitation attempts. The implementation should follow industry best practices established by NIST SP 800-53 and OWASP Top Ten guidelines for secure web application development, ensuring that all responses include the necessary security headers to prevent downgrade attacks and maintain cryptographic integrity throughout the communication lifecycle.
The vulnerability demonstrates a classic example of security through obscurity failing in practice, as the absence of explicit security headers creates predictable attack surfaces that malicious actors can exploit with minimal technical sophistication. Organizations deploying HCL DFXAnalytics or similar applications must recognize that modern web security requires proactive implementation of security controls rather than relying on client-side security measures or user awareness alone. The remediation process should include comprehensive testing to ensure proper header implementation across all application endpoints and regular vulnerability assessments to validate the effectiveness of the implemented security controls against evolving threat landscapes.
