Sensitive cookie without HttpOnly attribute
Description
The cookie was transmitted in a Set-Cookie
header without the HttpOnly
attribute set.
To prevent JavaScript being able to access the cookie value - usually via document.cookies
- all
cookies that are used for authorization should have the HttpOnly
attribute
set.
Remediation
Most web application frameworks allow configuring how cookies are sent to user-agents. Consult your framework’s documentation for more information on how to enable various security directives when assigning cookies to clients.
If the application is assigning cookies via writing to the response headers directly, ensure all responses include
the HttpOnly
attribute. By enabling this protection, the application is able to mitigate the impact of
certain Cross-Site Scripting (XSS) attacks.
Example:
Set-Cookie: {cookie_name}=<random secure value>; HttpOnly
