CVE-2020-7998
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 · uneditedAn arbitrary file upload vulnerability has been discovered in the Super File Explorer app 1.0.1 for iOS. The vulnerability is located in the developer path that is accessible and hidden next to the root path. By default, there is no password set for the FTP or Web UI service.
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 confidenceAn arbitrary file upload vulnerability in Super File Explorer iOS app 1.0.1 allows remote attackers to upload malicious files via an unprotected developer path hidden adjacent to the root path. The FTP and Web UI services have no password protection by default, enabling unauthenticated attackers to exploit the file upload 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.
-
Verify Super File Explorer versionCheck the installed version of Super File Explorer on the iOS device through the App Store purchase history, device settings, or by opening the app and navigating to the About/Settings section to confirm version 1.0.1 is installedAffected if The app version is exactly 1.0.1
-
Confirm FTP service is runningUse a network scanner or FTP client to probe the device on common FTP ports (21) or check within the app settings if the FTP server feature is enabledAffected if FTP service is enabled and running on the device
-
Test FTP access without authenticationAttempt to connect to the device FTP server using an FTP client without providing any credentialsAffected if FTP server accepts connections and allows file listing/upload without requiring a password
-
Confirm Web UI is accessibleOpen a web browser and navigate to the device IP address on common HTTP ports (8080, 80) or check within the app for Web UI access URLAffected if Web UI service is enabled and accessible via browser
-
Test Web UI access without authenticationAttempt to access the Web UI URL without providing any login credentialsAffected if Web UI loads and allows file operations without requiring authentication
-
Check for developer path exposureAttempt to access known developer paths adjacent to root such as /dev/, /admin/, /developer/ or similar paths relative to the Web UI or FTP rootAffected if An unprotected developer path is accessible and allows file upload operations
A user is affected if they have Super File Explorer version 1.0.1 installed with FTP or Web UI services enabled, and those services are accessible without authentication, exposing the unprotected developer path for file upload.

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 strong authentication for FTP and Web UI services, remove or restrict the exposed developer path, and add server-side validation to restrict allowed file types and locations.
