CVE-2024-0849
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 · uneditedLeanote version 2.7.0 allows obtaining arbitrary local files. This is possible because the application is vulnerable to LFR.
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 confidenceLeanote 2.7.0 is vulnerable to Local File Retrieval (LFR), allowing attackers to read arbitrary local files on the server via path traversal in file handling functionality.

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 Leanote Desktop versionCheck the application version by looking in the application metadata, about dialog, or version file included with the installation. On Windows this may be in the executable properties; on macOS check the app bundle info.plist.Affected if Version is exactly 2.7.0
-
Identify file handling functionality exposureLocate and inspect the file handling modules or endpoints in the Leanote installation. Look for file download, export, or retrieval functions in the source code or API handlers.Affected if File handling functionality is present and accessible to users or unauthenticated attackers
-
Check for path traversal vulnerabilityIf you have access to the application source or can intercept requests, examine how file path parameters are handled in the file retrieval feature. Look for code that accepts user-supplied paths without proper sanitization.Affected if The application accepts file path parameters and performs file operations without validating or sanitizing path traversal sequences like ../
-
Test path traversal in file operationsIf you can interact with the file handling feature, attempt a controlled test request with a path containing ../ sequences pointing to a known file outside the intended directory.Affected if The application allows reading files outside the intended directory via path traversal
A user is affected if Leanote Desktop version 2.7.0 is installed and the file handling functionality is accessible and accepts unsanitized path parameters.

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 and sanitization on file path parameters, ensuring paths are restricted to allowed directories and canonicalized to prevent directory traversal sequences.
