Check and help resolving VAPT reported issues Global Protect SSL VPN Url

We have done VAPT on our Global protect URL link and identified 3 VA,
Kindly check and help resolving this at earliest.

1) Absence of CSRF tokens :-

No Anti-CSRF tokens were found in a HTML submission form.
A cross-site request forgery is an attack that involves forcing a victim to send an HTTP request to a target destination without their knowledge or intent in order to perform an action as the victim. The underlying cause is application functionality using predictable URL/form actions in a repeatable way. The nature of the attack is that CSRF exploits the trust that a web site has for a user. By contrast, cross-site scripting (XSS) exploits the trust that a user has for a web site. Like XSS, CSRF attacks are not necessarily cross-site, but they can be. Cross-site request forgery is also known as CSRF, XSRF, one-click attack, session riding, confused deputy, and sea surf.

 

2) Missing secure Flag Attributes in the Encrypted Session (SSL) Cookie:-

The Session Cookie Does Not Have "Secure" Attribute.The Secure Attribute Tells The Browser To Only Use This Cookie Via Secure/Encrypted Connections. This measure makes certain client-side attacks, such as cross-site scripting, slightly harder to exploit by preventing them from trivially capturing the cookie's value via an injected script.


3) Referrer-Policy Header is not implemented:-

It was observed that, Referrer-policy is not implemented in response header.
Referrer-Policy is a security header designed to prevent cross-domain referrer leakage.
