CVE-2026-35143 in DFXAnalytics
Summary
by MITRE • 07/16/2026
HCL DFXAnalytics is affected by a Missing SameSite Attribute vulnerability. The application fails to set the "SameSite" attribute on session cookies generated during authentication, which could allow a remote attacker to execute Cross-Site Request Forgery (CSRF) attacks if additional mitigations, such as Anti-CSRF tokens, are not implemented.

The HCL DFXAnalytics platform presents a critical security weakness through its failure to implement the SameSite attribute on session cookies during authentication processes. This vulnerability creates an exploitable condition where remote attackers can leverage cross-site request forgery techniques to compromise user sessions and potentially gain unauthorized access to sensitive data or functionality within the application environment. The absence of proper cookie security controls fundamentally undermines the application's ability to protect against automated malicious requests that originate from third-party domains.
This specific flaw aligns with CWE-16, which addresses issues in the design of security-relevant controls, and represents a classic implementation gap in web application security practices. The vulnerability operates through the fundamental principle that session cookies without SameSite attributes are susceptible to being included in cross-site requests by browsers, thereby enabling attackers to trick authenticated users into performing unintended actions on the vulnerable application. The attack vector specifically targets the browser's cookie handling mechanisms where requests initiated from malicious domains can automatically include session cookies from legitimate applications.
The operational impact of this vulnerability extends beyond simple session hijacking scenarios to encompass potential data manipulation, unauthorized transactions, and privilege escalation within the DFXAnalytics environment. Attackers can craft malicious web pages or exploit existing social engineering techniques to execute CSRF attacks that leverage the victim's authenticated browser session without requiring knowledge of session tokens or other credentials. This creates a persistent threat vector that remains active as long as the vulnerable application continues to operate without proper cookie security configuration.
Organizations utilizing HCL DFXAnalytics should implement immediate mitigations including the mandatory configuration of SameSite attributes on all session cookies with values set to either 'Strict' or 'Lax' depending on the specific application requirements. The implementation should follow industry best practices and align with NIST SP 800-53 security controls for web application security, ensuring that cookie attributes are properly configured during the authentication process. Additionally, organizations must conduct comprehensive security assessments of their applications to identify all cookie-based session management mechanisms and verify proper SameSite attribute implementation across all authenticated paths.
Security teams should also consider implementing additional CSRF protection measures such as anti-CSRF tokens in conjunction with the SameSite attribute configuration, as recommended by the OWASP Top Ten project and ATT&CK framework's web application exploitation techniques. The combination of these mitigations creates a defense-in-depth approach that significantly reduces the risk surface for CSRF attacks while maintaining proper application functionality and user experience. Regular security testing and monitoring should be implemented to ensure ongoing compliance with cookie security standards and to detect any potential regressions in the implementation of SameSite attributes across the application infrastructure.
