Description

  1. SN headers have Strict-Transport-Security: max-age=31536000; includeSubDomains
    max-age=31536000 → 1 year browser cache to enforce HTTPS after first visit.
    includeSubDomains → applies to all subdomains too.
    But no preload flag.
    That means, when victim tries to visit stacker.news for the first time, he can:
  • ARP Spoof to become MITM.
  • iptables to DROP or RESET packets to 443 (HTTPS port).
  • DNS Spoof stacker.news to your own IP using bettercap
  • Serve fake stacker.news over HTTP (port 80).
  • Capture login details / sessions.
  • Once user submits anything → SN Rooted.

Fix: Strict-Transport-Security: max-age=63072000; includeSubDomains; preload
HSTS preload = browser already knows "always HTTPS" even before asking the server.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
