CVE-2024-45276
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 unauthenticated remote attacker can get read access to files in the "/tmp" directory due to missing authentication.
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 information disclosure vulnerability where missing authentication controls on an endpoint allows unauthenticated remote attackers to read arbitrary files in the system's /tmp directory. This could expose sensitive temporary files, session data, or other artifacts stored there.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 device model and firmware versionAccess the device's web interface or administrative CLI and locate the firmware version information, typically found in system status, about, or diagnostics sectionsAffected if The device is a Mbconnectline Mbnet.mini or Helmholz Rex 100 with firmware version lower than 2.3.1
-
Verify the vulnerable endpoint is accessibleAttempt to access the device's web interface or API endpoint that handles file operations without providing any authentication credentials. Check if the endpoint responds without requiring loginAffected if The endpoint responds to unauthenticated requests and allows access to file listing or retrieval functions
-
Confirm the file read capability existsTest the endpoint by attempting to access files in the /tmp directory using the vulnerable path, such as a URL like /tmp/<filename> or similar path traversal pattern if applicableAffected if The endpoint allows reading files from the /tmp directory without authentication
-
Check for sensitive data in /tmpIf the endpoint is accessible, enumerate files in /tmp to see if sensitive information such as configuration files, session data, credentials, or other temporary artifacts are presentAffected if Sensitive or confidential files exist in /tmp that could be accessed through the unauthenticated endpoint
You are affected if you have a Mbconnectline Mbnet.mini or Helmholz Rex 100 device running firmware below version 2.3.1 with the unauthenticated file access endpoint exposed.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped2.3.1
Implement proper authentication and authorization checks on the affected endpoint to ensure only legitimate, authenticated users can access files. Additionally, avoid storing sensitive data in /tmp or ensure strict file permissions.
Mbnet.mini Firmware >= 2.3.1 | Rex 100 Firmware >= 2.3.1
- Obtain Mbnet.mini Firmware version 2.3.1 or later from the official vendor (refer to cert.vde.com)
- Obtain Rex 100 Firmware version 2.3.1 or later from the official vendor (refer to cert.vde.com)
- Follow the vendor's official firmware upgrade procedure for the Mbnet.mini device
- Follow the vendor's official firmware upgrade procedure for the Rex 100 device
- Verify the firmware upgrade was successful and the device is operational
