Executive Summary

HCL IEM is missing the X-Content-Type-Options header, which could allow attackers to perform SSL stripping or man-in-the-middle attacks. This may lead to interception of sensitive data during transmission.

Detection Guidance

To detect the missing X-Content-Type-Options header in HCL IEM, you can use tools like curl or browser developer tools to inspect HTTP responses. For example, use curl -I <target_URL> to check headers. If the header is missing, it will not appear in the response.

Impact Analysis

This vulnerability could allow attackers to intercept sensitive data, such as login credentials or personal information, by exploiting man-in-the-middle attacks or SSL stripping.

Compliance Impact

Missing security headers like X-Content-Type-Options may violate compliance requirements for data protection, potentially leading to non-compliance with GDPR or HIPAA due to insufficient safeguards against data interception.

Mitigation Strategies

Immediately configure your web server or application to include the X-Content-Type-Options: nosniff header in all HTTP responses. This can typically be done via server configuration files or application code.
