CVE-2024-11312
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 confidenceDVC from TRCore contains a path traversal vulnerability combined with unrestricted file upload functionality. Unauthenticated remote attackers can upload arbitrary files to any directory on the server, enabling webshell deployment and resulting in arbitrary 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.
-
Determine installed DVC versionLocate the version information for Trcore DVC by checking the application documentation, administration panel, or version file typically found in the installation directory or system information pageAffected if The installed version is 6.0 or higher but lower than 6.4
-
Verify authentication is required for file upload functionalityInspect the file upload endpoint or service configuration to confirm whether authentication is enforced before allowing file upload requestsAffected if File upload endpoints are accessible without authentication or authentication can be bypassed
-
Check for path traversal validation in upload logicReview the file upload handling code or configuration to determine if paths are validated to prevent directory traversal sequences (such as ../)Affected if No path traversal validation exists or validation can be bypassed
-
Confirm file type restrictions on uploadsExamine the upload mechanism to verify if only safe whitelisted file extensions are permittedAffected if No file type restrictions exist or all file types are accepted
The environment is affected if Trcore DVC version is 6.0 or higher but below 6.4 AND the file upload feature is accessible without proper authentication or path validation controls.

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
Implement strict path traversal prevention by validating and sanitizing all file paths, restrict uploaded file types to safe whitelisted extensions, and enforce authentication for all file upload operations.
6.4 or later
- Backup your current Dvc installation and configuration data
- Review the official TRCore/Dvc release notes for version 6.4 to understand changes and ensure compatibility
- Download Dvc version 6.4 or later from the official TRCore vendor source (www.twcert.org.tw or vendor's official distribution channel)
- Stop the Dvc service or application
- Install the upgraded Dvc version following vendor-provided installation documentation
- Restart the Dvc service
- Verify the installation was successful and the service is running correctly
- Test that the path traversal vulnerability is no longer exploitable by attempting to access files outside the intended directory
