CVE-2021-29398
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDirectory traversal in /northstar/Common/NorthFileManager/fileManagerObjects.jsp Northstar Technologies Inc NorthStar Club Management 6.3 allows remote unauthenticated users to browse and list the directories across the entire filesystem of the host of the web application.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDirectory traversal vulnerability in /northstar/Common/NorthFileManager/fileManagerObjects.jsp of NorthStar Club Management 6.3 allows remote unauthenticated attackers to browse and list directories across the entire host filesystem by manipulating path traversal sequences.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm NorthStar Club Management installation and versionCheck for the NorthStar Club Management application on the server. Look for installation directories, banner grab the web application, or check version files. The affected version is exactly 6.3.Affected if The installed version is NorthStar Club Management 6.3 exactly.
-
Locate the vulnerable fileManagerObjects.jsp fileSearch the web root for the path /northstar/Common/NorthFileManager/fileManagerObjects.jsp. Check if this file exists on the server filesystem.Affected if The file fileManagerObjects.jsp exists at the expected path within the NorthStar installation.
-
Verify the endpoint is externally accessibleAttempt to access the full URL pattern: http://[host]/northstar/Common/NorthFileManager/fileManagerObjects.jsp via HTTP/HTTPS request. Confirm the application responds to this endpoint.Affected if The endpoint returns an HTTP response (any status code other than 404) indicating the file is accessible.
-
Check if path traversal protection is absentReview the application's input validation or security configuration for the fileManager endpoint. Look for filtering of '../' sequences or other path traversal protection mechanisms.Affected if No input validation or path traversal protection is implemented for this endpoint, allowing '../' sequences to pass through.
The environment is affected if NorthStar Club Management version 6.3 is running and the /northstar/Common/NorthFileManager/fileManagerObjects.jsp endpoint is accessible without path traversal protections in place.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation to reject path traversal sequences (../) and restrict the application's filesystem access to only necessary directories; consider removing or securing the fileManagerObjects.jsp endpoint if not required.
