All the files in this repository are client utilities expected to served from a webserver to run inside a web browser. Directly accessing the index.html file inside a browser will NOT work as most browsers will not allow network activity from static files on your local or network attached drive/storage.
Clone this repository to a web accessible folder in your webserver says into a folder called cveClient using git command git clone https://github.com/CERTCC/cveClient. Once you have cloned this folder, you can visit your webserver's relative URL at /cveClient/ to the folder where the repository was cloned. Ensure your webserver's default index file is index.html
If you use Content-Security-Policy (CSP) headers on your webserver or on your web reverse proxy, make sure the appropriate domain URLs are allowed for the folder that was cloned (cveClient). Below is the sample Content-Security-Policy header recommended for this folder:
