CVE-2014-2276
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 FileUploadController servlet in EMC Connectrix Manager Converged Network Edition (CMCNE) before 12.1.5 does not properly restrict additions to the Connectrix Manager repository, which allows remote attackers to obtain sensitive information by importing a crafted firmware file.
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 confidenceThe FileUploadController servlet in EMC Connectrix Manager Converged Network Edition prior to version 12.1.5 fails to properly restrict file uploads to the Connectrix Manager repository. This allows remote attackers to import crafted firmware files, potentially leading to unauthorized access to sensitive information through malicious file placement.

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 installed EMC Connectrix Manager versionAccess the product's About or System Information page through the management console, or check the installer logs and version file typically found in the product installation directory. Run the command 'cmcne -version' if available, or inspect the file 'CMCNEVersion.txt' in the installation path.Affected if The installed version is 12.1.2 or lower (any version <= 12.1.2).
-
Confirm FileUploadController servlet is present and accessibleCheck if the web application exposes the FileUploadController endpoint. This is typically accessible at a URL path containing '/FileUploadController' or similar. Attempt a GET request to the suspected endpoint (such as '/CMCNE/FileUploadController' or '/connectrix/FileUploadController') using a web browser or curl tool.Affected if The servlet responds or returns any HTTP status code other than 404 (not found), indicating it is deployed and accessible.
-
Verify authentication is required for file upload functionalityTest the FileUploadController endpoint by attempting an unauthenticated or low-privilege file upload request. Use a tool like curl to send a POST request to the servlet with a test file. Observe whether the request is accepted without credentials or proceeds despite lacking proper authentication.Affected if The servlet accepts file uploads without requiring valid authentication credentials, or allows uploads from unauthenticated network sources.
-
Inspect the firmware repository for unauthorized filesLocate the firmware repository directory on the Connectrix Manager server (commonly found under the product's data or repository folder). List all files in this directory and examine filenames, sizes, and upload timestamps. Look for any unexpected or suspiciously named files that were not uploaded through legitimate firmware update procedures.Affected if The repository contains files that do not match known legitimate firmware packages, or contains files with unusual extensions, abnormal timestamps, or that were added without corresponding authorized upload activity.
You are affected if your EMC Connectrix Manager version is 12.1.2 or earlier AND the FileUploadController servlet is exposed without proper authentication controls, or if unauthorized files are present in the firmware repository.

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 dataUpgrade to EMC Connectrix Manager CMCNE version 12.1.5 or later. If immediate patching is not possible, implement network-level access controls to restrict unauthorized access to the FileUploadController servlet and validate all uploaded firmware files before repository acceptance.
