CVE-2024-11311
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 · uneditedThe DVC from TRCore has a Path Traversal vulnerability and does not restrict the types of uploaded files. This allows unauthenticated remote attackers to upload arbitrary files to any directory, leading to arbitrary code execution by uploading webshells.
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 · moderate confidenceThe DVC product from TRCore contains a critical path traversal vulnerability combined with unrestricted file upload functionality. This allows unauthenticated remote attackers to write arbitrary files to any directory on the server, which can be leveraged to upload webshells and achieve remote code execution.

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 the installed DVC versionAccess the DVC admin interface or check the product's version information file (typically found in the installation directory or via /api/version endpoint). Compare the version number against the affected range: >= 6.0 and < 6.4.Affected if The installed version falls between 6.0 and 6.3.x inclusive.
-
Verify if unauthenticated file upload endpoints are exposedIdentify the file upload API endpoints in DVC (commonly /upload, /api/upload, or similar). Attempt to access these endpoints without authentication using a tool like curl or by inspecting the application's routing configuration.Affected if File upload endpoints are accessible without requiring authentication.
-
Inspect upload functionality for path traversal capabilitySend a file upload request containing path traversal sequences in the filename parameter (for example, ../../shell.jsp) and verify if the server allows writing files outside the designated upload directory.Affected if The application accepts path traversal sequences and writes files to directories outside the intended upload folder.
-
Determine if upload directories allow script executionLocate the configured upload directory in DVC configuration files (such as config.xml, application.properties, or similar). Check if this directory is located within a web-accessible path that permits executing uploaded scripts (for example, within /webapps or /public folders).Affected if Uploaded files can be stored in directories that are web-accessible and allow script execution.
You are affected if running Trcore Dvc version 6.0 through 6.3.x with unauthenticated file upload endpoints exposed to the network.

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.
dbcve · scoped6.4
Disable unauthenticated file upload access, implement strict allowlist-based file type validation, sanitize and validate all path inputs to prevent directory traversal sequences, and restrict upload directories to non-executable locations.
DVC version 6.4 or later
- Check the current installed version of DVC using 'dvc --version' or similar command
- Back up all DVC configuration files, repositories, and data
- Download DVC version 6.4 or later from the official TRCore source
- Install the updated version following the vendor's installation instructions
- Verify the new version is installed correctly by running 'dvc --version'
- Test that the path traversal vulnerability is no longer present by confirming file upload restrictions work as expected
- Ensure all DVC functionality operates normally after the upgrade
