CVE-2023-48245
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 · uneditedThe vulnerability allows an unauthenticated remote attacker to upload arbitrary files under the context of the application OS user (“root”) via a crafted HTTP request.
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 confidenceThis is an unauthenticated arbitrary file upload vulnerability allowing remote attackers to upload any file to the affected system, executing with root privileges. The vulnerability is exploited via crafted HTTP requests to file upload functionality that lacks proper validation, authentication, and access controls.

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.
-
Identify the product and versionLocate the Bosch Nexo Os installation and determine the installed version number. Consult system documentation or use vendor-provided version inspection commands to retrieve the exact version string.Affected if The installed version is Bosch Nexo Os version 1000 through 1500-sp2 inclusive.
-
Verify file upload functionality is exposedIdentify whether the system's file upload web endpoints or APIs are accessible from the network. Review exposed network services, web interfaces, or API endpoints that handle file uploads.Affected if File upload functionality is reachable without requiring authentication or access credentials.
-
Check authentication requirements on upload endpointsTest file upload endpoints by sending unauthenticated HTTP requests with a benign file to see if the system accepts the upload without rejecting it due to missing credentials or session tokens.Affected if The system accepts and processes file upload requests without requiring valid authentication.
-
Inspect access controls on upload functionalityReview the system's access control configuration, permissions, or security settings for the file upload module to determine if any allowlist, role-based restrictions, or validation logic is present.Affected if No access controls, authentication requirements, or validation logic are enforced on file upload operations.
You are affected if the system is Bosch Nexo Os version 1000-1500-sp2 and the file upload functionality is exposed without authentication or access controls.

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 file upload validation including authentication requirements, file type whitelisting, file content inspection, storage outside webroot, and disable script execution in upload directories to prevent uploaded malicious files from being executed.
