What it is
An action never checks whether the caller is allowed to perform it.
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
A successful attack can read the data it protects. In practice, this kind of flaw lets an attacker reach data or actions their role should not allow.
Is it being exploited?
CISA's SSVC assessment notes a public proof of concept.
What to do
- Upgrade freescout-help-desk freescout to 1.8.231 or later.
- Until it is patched, review who holds accounts that can reach it.
Description from NVD
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.231, when limit_user_customer_visibility is enabled, the load_customer_info AJAX action performs a global lookup using an attacker-controlled customer email and checks only whether the agent can access a separately supplied mailbox. A non-admin agent can name an accessible mailbox and retrieve an unrelated customer's rendered profile without invoking CustomerPolicy::view(). The response can expose names, email addresses, phone numbers, company and job information, postal addresses, social profiles, websites, and confidential internal agent notes. This issue is fixed in version 1.8.231.
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 freescout-help-desk freescout 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?
