The vendor was contacted early about this disclosure but did not respond in any way.
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 Acrel Electrical Prepaid Cloud Platform 1.0 exposes a backup archive file (/bin.rar) via the Backup File Handler component, allowing remote attackers to download the file and potentially extract sensitive system information, configuration data, or credentials.

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.
-
Confirm the Acrel Electrical Prepaid Cloud Platform is deployedCheck your web server or application inventory for the presence of the Acrel Electrical Prepaid Cloud Platform version 1.0. Look for application banners, installed components, or running services matching this product name.Affected if The product is not installed in your environment, this CVE does not apply.
-
Check if the backup file exists on the serverIf you have server access, search for the file /bin.rar within the web application directory structure. The file may be located in the web root or a backup directory.Affected if The file /bin.rar does not exist on your server, you are not affected by this exposure.
-
Test public access to the backup fileAttempt to access the URL pattern: http(s)://<your-domain-or-ip>/bin.rar using a web browser or curl command. Check if the file downloads successfully without authentication.Affected if The /bin.rar file returns an HTTP 200 response and downloads, your environment is affected by this vulnerability.
-
Inspect web server access logs for the pathReview your web server access logs (Apache, Nginx, IIS) for requests to /bin.rar. Look for GET requests that returned 200 status codes indicating successful file access.Affected if Unauthorized external requests to /bin.rar appear in your logs, the vulnerability has been exploited.
You are affected if the Acrel Electrical Prepaid Cloud Platform 1.0 is running and the /bin.rar file is publicly accessible via HTTP/HTTPS without authentication.

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 dataRestrict access to backup files by moving them outside the webroot or implementing proper authentication/authorization controls on the /bin.rar endpoint. Remove publicly accessible backup files from production systems.
