Pensar - auto fix for Missing Authentication Check in Admin Page Access

[pensarapp]

Fixed a critical authorization vulnerability (CWE-862: Missing Authorization) in the AdminPage component. The original code redirected users to admin pages without any authentication or authorization checks, allowing unauthorized access to administrative functionality.

The fix implements a defense-in-depth approach with two security layers:

1. Added an isAuthenticated() function that checks if the user is logged in by verifying the presence of an auth token in cookies
2. Added a hasAdminPermission() function that verifies if the authenticated user has admin privileges

The component now performs these checks before redirecting to admin pages:

• If the user is not authenticated, they are redirected to a login page
• If the user is authenticated but lacks admin permissions, they are redirected to an unauthorized page
• Only users who pass both checks are redirected to the admin pages

Note that the implementation uses Next.js built-in cookies API and provides template implementations that must be customized to work with the application's actual authentication system. The placeholder implementations deliberately return false for authorization checks as a secure default.

Type	Identifier	Message	Severity	Link
Application	CWE-862	The AdminPage component lacks any authentication or authorization checks before redirecting to the admin pages. This omission may allow unauthorized users to access administrative functionality if the surrounding access control is not enforced elsewhere, resulting in an authorization bypass vulnerability (CWE-862). Although the redirect path is hardcoded and not controlled by user input, the absence of any authentication control is critical, particularly in an administrative context.	high	Link
