Readycheck to confirm it

A directory traversal vulnerability in the st module before 0.2.5 for Node.js allows remote attackers to read arbitrary files via a %2e%2e (encoded dot dot) in an unspecified path.

Impact

An attacker can read sensitive files on the server, potentially leading to unauthorized access or exposure of sensitive information.

Fix

Upgrade to a patched version of the st module or use an alternative module that is not vulnerable to directory traversal.

How to confirm it

Send: GET {{BaseURL}}/public/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/etc/passwd
Positive when: matches /root:.*:0:0:/ AND status 200
