An Unauthenticated Insecure Direct Object Reference (IDOR) vulnerability was identified that allows an unauthenticated attacker to access guest address information without supplying valid credentials or session cookies.
During testing, it was observed that all guest users can make an unauthenticated request to retrieve address data belonging to other guest users by manipulating object identifiers. The attacker would need to know the storefront URL structure to perform this attack (which can be learnt after creating a registered user account).
Affected Component(s)
/addresses/{addressId}/editRoot Cause
- can :manage, ::Spree::Address, user_id: user.id
+ can :manage, ::Spree::Address, user_id: user.id if user.persisted?
the user object in Spree::Ability class for guest users is a Spree.user_class.new object.
Addresses endpoint to access it is part of the spree_storefront gem. Headless builds using APIs are not affected, as the Addresses endpoint there is only for registered users, and records are scoped to the currently signed-in user.
Preconditions
To reproduce this vulnerability simply perform the request shown below, replacing the number with an arbitrary value.
For the initial request the Guest Address id = 6 is used to obtain the information
Request
GET /addresses/6/edit
Repeat the request and check the response, in this example using Guest Address id = 2.
Request
GET /addresses/2/edit
An unauthenticated attacker can:
