  • Look for HTTP GET requests containing URL-encoded dot-dot sequences (%2e%2e) in the path, particularly under a /public/ directory prefix, targeting sensitive files such as /etc/passwd.
  • A successful exploitation response will return HTTP 200 with content matching the regex 'root:.*:0:0:' indicating /etc/passwd was read.
  • The attack path pattern to detect is: /public/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/etc/passwd — five levels of encoded traversal from a static-serving mount point.
  • ·Vulnerability only affects the Node.js 'st' module versions before 0.2.5; systems running st >= 0.2.5 are not affected.
  • ·The traversal path used in the nuclei template assumes the static files are served under a /public/ mount point; actual mount points may differ per deployment, requiring path adjustment in detection rules.
