Information Disclosure via X-Cocoon-Version Header

Description

The 'X-Cocoon-Version' header indicates that the application is using Apache Cocoon or a related framework, potentially revealing the specific version or build. Attackers can leverage this information to target known vulnerabilities, outdated libraries, or default configurations in Apache Cocoon. By pinpointing the version, malicious actors may craft more tailored exploits, conduct recon on default endpoints, or pursue social engineering tactics referencing Cocoon-specific features. Disclosing such internal framework details increases the risk of exploitation, as adversaries can narrow their focus to vulnerabilities confirmed within the identified Cocoon release.

Remediation

Remove or mask the 'X-Cocoon-Version' header to avoid advertising the framework or version to unauthorized users. Update the Apache Cocoon setup to the latest secure release, applying patches and security advisories from the Cocoon community. If you deploy load balancers, proxies, or CDNs, configure them to block or sanitize headers that leak framework details. Consider employing a Web Application Firewall (WAF) or intrusion detection system to detect and intercept potential Cocoon-oriented attacks. Finally, regularly audit all server and application configurations to confirm that sensitive headers are stripped, keeping framework information private.
