CVE-2023-5079
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 · uneditedLenovo LeCloud App improper input validation allows attackers to access arbitrary components and arbitrary file downloads, which could result in information disclosure.
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 Lenovo LeCloud App has improper input validation that allows attackers to access arbitrary application components and download arbitrary files from the system, likely through path traversal or similar injection techniques. This enables unauthenticated information disclosure of sensitive data accessible to the application.

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.
-
Verify Lenovo LeCloud is installedCheck the system for the presence of the Lenovo LeCloud application - look in installed programs on Windows, application list on Android, or package manager on LinuxAffected if The application is not found, the vulnerability does not apply
-
Identify installed version of Lenovo LeCloudAccess the application's 'About' or 'Settings' section, or use system package management tools to query the installed version numberAffected if Unable to determine the version - assume potentially affected if the app is present
-
Compare version against affected rangeTake the identified version number and compare it to the affected range: any version less than 7.0.25.99 is considered vulnerableAffected if Installed version starts with a number less than 7.0.25.99 (e.g., 7.0.25.98, 6.x.x.x, 5.x.x.x), or begins with 7.0.25 but ends below .99
-
Confirm app handles user-supplied file pathsReview application functionality that accepts file paths, shares, or external inputs - check if the app has features for file browsing, cloud sharing, or external storage access where user paths could be providedAffected if The app has features accepting file paths or external input that could be manipulated through path traversal techniques
User is affected if Lenovo LeCloud is installed with any version below 7.0.25.99 and the application processes user-supplied paths or file inputs that could be exploited for unauthorized file access.

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 · scoped7.0.25.99
Implement strict server-side input validation, sanitize all user-supplied paths, and enforce proper access control checks to prevent directory traversal and unauthorized component/file access.
7.0.25.99 or later
- 1. Identify the current installed version of Lenovo LeCloud application
- 2. Navigate to the official Lenovo support or application download page
- 3. Download Lenovo LeCloud version 7.0.25.99 or the latest available version
- 4. Backup any existing data stored in the LeCloud application
- 5. Uninstall the current version of LeCloud
- 6. Install the new version (7.0.25.99 or later)
- 7. Verify the installation was successful and the application runs without errors
- 8. Test that the previously vulnerable functionality now works correctly
