Element Code: SE-004
Quick Reference
Issue: HTTP headers reveal server software and version information
Impact: Attackers can target known vulnerabilities in specific versions
Fix: Remove or obfuscate Server, X-Powered-By headers
Detection: HTTP header inspection, security scanners
What Is This Issue?
Headers like Server and X-Powered-By reveal your technology stack and versions. Attackers can use this to find known exploits for your specific software versions.
Why This Matters for Your Website
While not directly exploitable, this information helps attackers. Security through obscurity is not the main defense but every bit helps.
How to Fix This Issue
- Remove headers: Configure server to hide version info
- Apache: ServerTokens Prod, ServerSignature Off
- Nginx: server_tokens off;
Tools for Detection
- Security scanners: Flag information disclosure
TL;DR (The Simple Version)
Your server headers reveal what software and versions you use. Remove or hide this information so attackers cannot easily target known vulnerabilities.
