Executive Summary

HCL IEM does not enforce strict transport security, which means secure HTTPS connections can be downgraded to insecure HTTP. This allows attackers to intercept or manipulate communications between users and the system.

Detection Guidance

This vulnerability involves lack of Strict Transport Security (HSTS) enforcement in HCL IEM, which could allow SSL stripping or man-in-the-middle attacks. Detection requires checking if HSTS headers are properly configured in HTTP responses from the IEM server. Use tools like curl to inspect headers: curl -I https://your-iem-server. If no 'Strict-Transport-Security' header is present or its settings are weak, the system is vulnerable.

Impact Analysis

Attackers could perform SSL stripping or man-in-the-middle attacks, potentially stealing sensitive data like login credentials or session tokens. This could lead to unauthorized access to systems or data.

Compliance Impact

This vulnerability may violate requirements for secure data transmission in GDPR and HIPAA, as both mandate encryption for protecting personal or health data. Non-compliance could result in legal penalties.

Mitigation Strategies

Enable strict transport security (HSTS) on HCL IEM to enforce HTTPS and prevent SSL stripping or man-in-the-middle attacks. Ensure all communications use encrypted channels and disable any fallback to insecure protocols.
