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
An arbitrary file upload vulnerability in the component /userPicture of Timo v2.0.3 allows attackers to execute arbitrary code via uploading a crafted file.

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 · high confidence

Arbitrary file upload vulnerability in the /userPicture endpoint of Timo v2.0.3 allows attackers to bypass file type validation and upload malicious files (e.g., web shells), which can then be accessed and executed to achieve arbitrary code execution on the server.

MitigationImplement strict allowlist-based file type validation (including magic byte verification), store uploads outside the web root, rename uploaded files, and disable script execution in upload directories.

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 if Timo is deployed
    Check running web services or application directories for Timo. Look for application banners, headers, or files containing 'Timo' branding. Inspect web server access logs for requests to Timo-specific paths.
    Affected if Timo web application is present in the environment
  2. Determine Timo version
    Review application source files, configuration files, or the application's about/version page. Check the login page, footer, or /api/version endpoint for version information.
    Affected if Installed version is Timo v2.0.3 exactly, or falls within version range where 2.0.3 is included without patch
  3. Verify /userPicture endpoint exists
    Send a GET or POST request to /userPicture or /api/userPicture. Check if the endpoint responds (even with an error indicating authentication is required).
    Affected if The /userPicture endpoint is accessible and responds to requests
  4. Check if file upload functionality is enabled
    Attempt to access the user profile or settings area where profile picture upload is available. Verify the upload form exists and accepts file input.
    Affected if User profile picture upload feature is enabled and accessible to the user
  5. Inspect upload directory configuration
    Review web server and application configuration to locate where uploaded files are stored. Check if uploads are placed within the web root.
    Affected if Uploads are stored inside the web-accessible directory structure

User is affected if running Timo v2.0.3 with the /userPicture upload endpoint accessible and file upload functionality enabled.
