CVE-2026-56454 in DFXAnalytics
Summary
by MITRE • 07/16/2026
HCL DFXAnalytics is affected by a Deprecated Protocol vulnerability due to the use of TLS 1.0 and TLS 1.1. These legacy protocols contain numerous cryptographic design flaws that expose data to interception and decryption. To remediate this risk, the application must disable all support for TLS 1.0 and TLS 1.1, and exclusively enable support for secure protocols, specifically TLS 1.2 and TLS 1.3.

The HCL DFXAnalytics platform presents a significant security weakness through its reliance on deprecated cryptographic protocols, specifically TLS 1.0 and TLS 1.1 implementations. This vulnerability stems from the application's failure to enforce modern secure communication standards, creating an exploitable vector for man-in-the-middle attacks and data interception attempts. The use of these legacy protocols represents a fundamental flaw in the system's cryptographic posture that directly violates established security frameworks and best practices.
The technical implementation of TLS 1.0 and TLS 1.1 within HCL DFXAnalytics exposes the platform to multiple known cryptographic weaknesses including POODLE attacks, BEAST vulnerabilities, and insufficient forward secrecy mechanisms. These protocols lack modern security features such as secure key exchange algorithms, robust authentication mechanisms, and proper cryptographic hashing functions that are standard in contemporary implementations. The vulnerability manifests when network traffic flows through systems that support these outdated protocols, allowing attackers to potentially decrypt sensitive communications or manipulate data in transit.
From an operational standpoint, this vulnerability creates substantial risk exposure for organizations utilizing HCL DFXAnalytics as it enables adversaries to intercept and potentially modify data exchanges between the application and its users. The impact extends beyond simple data theft to include potential system compromise through credential interception, session hijacking, and unauthorized access to analytical data. This weakness directly correlates with CWE-327, which addresses the use of weak cryptographic algorithms and protocols that have known security vulnerabilities.
Security frameworks including NIST SP 800-52 and ISO/IEC 27001 require organizations to implement secure communication protocols and phase out support for deprecated cryptographic standards. The ATT&CK framework categorizes this vulnerability under T1566, representing credential access through network sniffing and protocol manipulation techniques. Organizations using HCL DFXAnalytics face compliance risks with regulations such as PCI DSS, HIPAA, and GDPR that mandate the use of secure communication protocols.
The remediation strategy requires comprehensive disabling of TLS 1.0 and TLS 1.1 support within the application's configuration settings and underlying cryptographic libraries. System administrators must ensure that all network components, including web servers, database connections, and API endpoints, are configured to exclusively support TLS 1.2 and TLS 1.3 protocols. This involves updating server configurations, modifying application code where necessary, and implementing proper certificate management for the newer protocol versions.
Additional mitigation measures should include regular security assessments to verify that no legacy protocol support remains active within the system architecture. Network monitoring solutions should be configured to detect and alert on any attempts to establish connections using deprecated protocols. Organizations should also implement automated patch management processes to ensure that all system components maintain current security configurations and that the transition to secure protocols is complete across all operational environments.
The vulnerability represents a critical gap in the platform's security architecture that requires immediate attention to prevent potential exploitation by threat actors who actively target systems using outdated cryptographic implementations. Regular security audits should verify that no legacy protocol support persists within the application ecosystem, ensuring complete compliance with current industry standards and regulatory requirements for secure communications.
