Information Disclosure via Product Header

Description

The 'Product' header discloses the specific software or system your application is built upon, thereby revealing part of its technology stack. Attackers can use this information to discover known vulnerabilities, outdated versions, or typical misconfigurations tied to that particular product. By pinpointing which product is in use, adversaries might create more tailored exploits or carry out targeted social engineering (e.g., phishing) that references your product. In some cases, publicly disclosing the product name can lead malicious actors to default admin panels or support endpoints. Overall, failing to hide or manage this header increases the risk of information disclosure and narrows an attacker’s research efforts.

Remediation

Remove or rename the 'Product' header to avoid revealing internal software details. Where possible, configure your server, framework, or application to disable technology-specific headers. Keep your product up to date with the latest security patches, and monitor any known vulnerabilities that might apply. Consider using a Web Application Firewall (WAF) or intrusion detection system to spot suspicious patterns exploiting product-related issues. Regular security reviews, including testing for unnecessary headers, will further help protect against unauthorized data exposure and product-specific exploits.
