CVE-2023-48246
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 a remote attacker to download arbitrary files in all paths of the system 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 a path traversal vulnerability allowing a remote attacker to download arbitrary files from any system path via crafted HTTP requests. The critical severity comes from the fact that the vulnerability runs with 'root' privileges, enabling access to sensitive system files including configuration files, credentials, and other critical data.

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 installed Bosch Nexo Os versionAccess the system administration interface or use the system's version command (such as 'sudo nexos version' or checking the About/System Info page in the management console). Compare the displayed version number against the affected range of >= 1000 to <= 1500-sp2.Affected if The installed version falls within 1000 through 1500-sp2 inclusive.
-
Verify the web management interface is accessibleConfirm that the Bosch Nexo Os web interface or API endpoint is reachable over HTTP/HTTPS. This vulnerability is exploited via crafted HTTP requests.Affected if The web management interface or REST API is exposed and accessible on the network.
-
Confirm the service runs with elevated privilegesCheck the process owner of the Nexo Os service by running 'ps aux | grep nexos' or reviewing the service configuration file. Verify if the process runs as the root user or with sudo privileges.Affected if The Nexo Os service process runs as root or with equivalent administrative privileges.
You are affected if your Bosch Nexo Os version is between 1000 and 1500-sp2 inclusive, the web interface is network-accessible, and the service runs with root-level privileges, as all three conditions are required for full exploitation of this path traversal vulnerability.

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 input validation and sanitization for all file path parameters, use allow-lists for permitted paths, and ensure the application runs with least-privilege rather than root.
