CVE-2015-7910
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 · uneditedExemys Telemetry Web Server relies on an HTTP Location header to indicate that a client is unauthorized, which allows remote attackers to bypass intended access restrictions by disregarding this header and processing the response body.
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 confidenceExemys Telemetry Web Server incorrectly uses an HTTP Location header redirect (302) to indicate unauthorized access instead of properly blocking the response. Attackers bypass this by ignoring the redirect and reading the response body, which contains sensitive telemetry data that should be protected.

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 if Exemys Telemetry Web Server is runningCheck running processes or services for 'Exemys' or 'Telemetry' web server components. Look for processes listening on common web ports (80, 443, 8080) associated with Exemys software.Affected if Exemys Telemetry Web Server process is found running
-
Test unauthorized access to telemetry endpointsSend an HTTP GET request to the telemetry web interface or API endpoints without providing any authentication credentials. Use a tool like curl with options to follow or ignore redirects.Affected if Request returns an HTTP 302 redirect response
-
Inspect response body of redirect responseCapture and examine the HTTP response body from the 302 redirect WITHOUT following the redirect automatically. Check if sensitive telemetry data (measurements, readings, system information) is present in the response body.Affected if The 302 response body contains telemetry data that should be protected
-
Verify sensitive data exposureCompare the data found in the 302 response body against expected protected telemetry parameters (such as sensor readings, equipment status, operational metrics). Confirm whether unauthorized users can access this data.Affected if Protected telemetry data is readable in the response body of a 302 redirect
If the Exemys Telemetry Web Server is running and returns a 302 redirect for unauthorized access but the response body still contains sensitive telemetry data, the environment is affected by CVE-2015-7910.

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 dataReplace client-side redirect-based access control with server-side authentication and authorization checks that reject unauthorized requests before returning any protected content.
