Dfxserver CVE-2026-35147

HCL DFXServer contains an authentication bypass vulnerability (CVE-2026-35147) allowing unauthenticated remote attackers to access sensitive API endpoints and retrieve confidential data. Organizations running this product face immediate exposure of sensitive information with no available vendor patch, requiring urgent network-based compensating controls.

Within 24 hours, identify and inventory all HCL DFXServer instances in your environment and document their network exposure and connected data classification. Within 7 days, restrict network access to DFXServer API endpoints via firewall rules or VPN segmentation, deploy Web Application Firewall rules to monitor and block suspicious API traffic, and enable comprehensive audit logging on all instances. Within 30 days, establish communication with HCL support to confirm patch release timeline, evaluate feasibility of upgrading to a patched version when available, and assess whether alternative products should replace DFXServer to mitigate ongoing risk.

Network segmentation restricting DFXServer API endpoint access to explicitly authorized internal networks; Web Application Firewall (WAF) deployed to block and log suspicious API access patterns; enhanced audit logging and real-time monitoring of all API requests to detect unauthorized access attempts; network-based authentication enforcement through VPN or firewall authentication requirements for all API consumers.
