CVE-2022-25242
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 · uneditedIn FileCloud before 21.3, file upload is not protected against Cross-Site Request Forgery (CSRF).
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 confidenceFileCloud before version 21.3 lacks anti-CSRF protection on file upload functionality, allowing attackers to craft malicious requests that trick authenticated users into uploading files to the server without their knowledge.

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.
-
Check installed FileCloud versionAccess the FileCloud admin panel or check the installation directory for version information. Typically found in admin settings or about page.Affected if The installed version is earlier than 21.3.0.18447
-
Verify file upload functionality is enabledCheck if the file upload feature is accessible to users in your FileCloud deployment. Navigate to user portal and confirm upload capability exists.Affected if File upload functionality is enabled and accessible to authenticated users on a vulnerable version
-
Inspect upload request for CSRF protectionUse browser developer tools or a proxy to intercept a file upload request. Examine the request headers and parameters for a CSRF token or anti-CSRF mechanism.Affected if No CSRF token or anti-CSRF parameter is present in the file upload request
You are affected if FileCloud version is earlier than 21.3.0.18447 and the file upload feature is accessible to authenticated users without CSRF protection tokens in upload requests.
