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 · unedited
File path manipulation vulnerability in BF-OS version 3.00 up to and including 3.83 allows an attacker to modify the file path to access different resources, which may contain sensitive information.

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 confidence

This is a path traversal vulnerability in BF-OS versions 3.00 through 3.83 where user-supplied file path input is not properly validated, allowing attackers to use '../' or absolute path sequences to escape the intended directory and access sensitive files outside the expected scope.

MitigationImplement strict input validation and canonicalization of file paths before use, ensuring paths resolve within allowed directories and rejecting paths containing 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify BF-OS version
    Locate the BF-OS installation directory and check the version information file or system info command (e.g., bosch_version, system_info, or check the firmware/metadata files in the installation folder)
    Affected if The installed version is 3.00, 3.01, 3.02, ..., up to and including 3.83 (any version >= 3.00 and <= 3.83 is affected)
  2. Confirm file path input feature is in use
    Identify whether BF-OS is configured to accept user-supplied file paths through any API, web interface, CLI parameter, or configuration setting that handles file operations
    Affected if The system accepts file path input from users or external sources for any file read/write operations
  3. Check for path traversal mitigation in file handling module
    Inspect the file handling configuration or source code module responsible for processing file paths, looking for input validation logic that checks for '../' sequences, absolute paths, or path canonicalization
    Affected if No traversal protection is found (the validation is missing or disabled) in the file path handling component
  4. Verify allowed directory restrictions
    Review the BF-OS configuration files or access control settings to determine if file operations are restricted to a specific base directory
    Affected if There is no enforced base directory constraint or allowlist defining where file operations can execute

You are affected if BF-OS version is between 3.00 and 3.83 inclusive AND the system accepts user-supplied file paths without proper traversal validation.
