CVE-2026-35147 HCL Software CVE debrief

Who should care

Security teams and administrators responsible for HCL DFXServer should assess and mitigate this Broken Authentication vulnerability. They should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Additionally, they should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed and review compensating controls for exposed systems while remediation is scheduled and verified.

Technical summary

HCL DFXServer is affected by a Broken Authentication vulnerability via direct API access. The application fails to verify the user's authentication status when accessing specific API endpoints, allowing an unauthenticated attacker to interact with the APIs and perform unauthorized actions without valid credentials. This vulnerability can be exploited by an attacker to perform unauthorized actions, potentially leading to security breaches. It is essential to verify and enforce proper authentication mechanisms for API endpoints, restrict access to sensitive API endpoints, and monitor for suspicious API activity.

Defensive priority

High priority due to the potential for unauthorized actions without valid credentials.

Recommended defensive actions

• Verify and enforce proper authentication mechanisms for API endpoints.
• Restrict access to sensitive API endpoints.
• Monitor for suspicious API activity.
• Implement additional security measures such as rate limiting and IP blocking.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
