You can insert malicious code in the title or other places on the interface to steal the account and password entered by the user and the current cookie information of the user after login. Once the vpn entry is attacked by hackers, the consequences are unimaginable, which may lead to the fall of the Intranet. Once the customer information is leaked, the loss will not be estimated. Due to the vulnerability test, you accidentally modified your main interface and hoped to include it, security is the first priority. I hope you can fix it as soon as possible to reduce losses.
