Published · Updated · NVD status: Awaiting Analysis
What it is
Changing an identifier in a request reaches another user's records.
How it is reached
An attacker can exploit it over the network, with an ordinary user account, and nobody has to click anything.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker reach data or actions their role should not allow.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- No fixed version is listed yet. Find every place Red Hat Satellite 6 runs, watch the references for a fix, and plan a replacement if it is no longer supported.
- While there is no fix, review who holds accounts that can reach it.
Description from NVD
A flaw was found in Foreman’s Api::V2::MailNotificationsController, where authorization checks on user-specific mail-notification resources are insufficient. The GET /api/v2/users/:id/mail_notifications endpoint resolves the target account using User.find(params[:id]) without verifying that the authenticated user is authorized to access that user’s notification configuration. Additionally, the POST and PUT /api/v2/users/:user_id/mail_notifications paths call deny_access when the requester is unauthorized but fail to halt execution, allowing the request to continue and persist the unauthorized change despite a 403 response or subsequent DoubleRenderError. This can allow a user to disclose another user’s mail-notification configuration, including mail_query values, and, where write permissions apply, modify or create notification settings for another user.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Permission checks in APIs and admin surfaces. The flaw sits between one role or tenant and another.
- Multi-tenant services. The flaw sits between one role or tenant and another.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Between one role or tenant and another. An attacker who crosses it can reach data or actions their role should not allow.
Questions to answer about your own systems
- Where does Red Hat Satellite 6 run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
