CVE-2015-4031
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 vulnerability in saveFile.jsp in the development installation in Visual Mining NetChart allows remote attackers to write to arbitrary files via unspecified vectors.
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 saveFile.jsp in the development installation of Visual Mining NetChart allows remote unauthenticated attackers to write to arbitrary files on the server by manipulating file paths in the saveFile.jsp endpoint.

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.
-
Identify Visual Mining NetChart installationSearch the server filesystem for NetChart or Visual Mining related directories, typically under the application server webroot (e.g., Tomcat webapps, JBoss, or similar). Look for folders named 'netcharts', 'visualmining', or containing 'NetChart' in filenames.Affected if Visual Mining NetChart software is present on the server
-
Locate the vulnerable saveFile.jsp endpointSearch for the file named 'saveFile.jsp' within the NetChart installation directory, particularly within a 'development' or 'demo' subdirectory.Affected if The file saveFile.jsp exists in the NetChart installation, especially under a development or demo path
-
Verify the development installation is deployedConfirm that the development/demo version of NetChart is deployed to a live application server and accessible over HTTP/HTTPS. Check web.xml or server configuration for the context path.Affected if The development installation is deployed and accessible via web server
-
Check network accessibility of the saveFile.jsp endpointAttempt to access the saveFile.jsp endpoint via HTTP/HTTPS from an external host using a tool like curl (e.g., curl http://target:port/path/saveFile.jsp).Affected if The saveFile.jsp endpoint is reachable over the network without authentication
-
Inspect the endpoint for traversal protectionReview the saveFile.jsp source code for lack of input validation on file path parameters. Look for absence of path normalization, whitelist checks, or traversal sequence (../) filtering.Affected if The saveFile.jsp lacks proper path validation and allows directory traversal patterns in file save requests
A user is affected if Visual Mining NetChart Server with the development saveFile.jsp endpoint is installed and network-accessible without authentication, as all versions are vulnerable to unauthenticated directory traversal file writes.

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 dataRemove or disable the development installation entirely, or at minimum restrict network access to saveFile.jsp until a vendor patch is available; implement strict path validation and whitelist-based file writing controls in the JSP to prevent traversal sequences.
