Improper Privilege Management (CWE-269)

Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

When privileges are not properly managed, users may gain access to resources or functionality they should not have. This includes privilege escalation and improper role assignment.

Default Privilege Assignment in User Creation HIGH

Create users with least-privilege defaults and require explicit admin action for privilege elevation

+4 -4 python

  def register(request):
      data = request.get_json()
-     user = User.objects.create(
-         username=data['username'],
-         email=data['email'],
-         is_staff=True,
+     user = User.objects.create_user(
+         username=data['username'],
+         email=data['email'],
+         password=data['password'],
      )
      return {'status': 'created'}

Missing Role/Permission Checks HIGH

Use permission decorators to verify user roles before any privilege modification

+5 -3 python

- from django.http import JsonResponse
- from django.contrib.auth.models import User
- 
+ from django.contrib.auth.decorators import permission_required
+ from django.http import JsonResponse
+ from django.contrib.auth.models import User
+ 
+ @permission_required('auth.change_user', raise_exception=True)
  def promote_user(request, user_id):
      user = User.objects.get(id=user_id)
      user.is_staff = True
      user.save()
      return JsonResponse({'status': 'promoted'})
