Why this priority: Medium severity, with no exploitation signal.

Published · Updated · NVD status: Received

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?

CISA's SSVC assessment notes a public proof of concept. EPSS estimates a 0.23% chance of exploitation activity in the next 30 days, higher than 14% of scored CVEs.

What to do

  1. No fixed version is listed yet. Find every place oss-apps SplitPro runs, watch the references for a fix, and plan a replacement if it is no longer supported.
  2. While there is no fix, review who holds accounts that can reach it.

Description from NVD

SplitPro through 2.1.6 contains an authorization bypass vulnerability that allows authenticated users to retrieve any account's details by supplying arbitrary userId values to user.getUserDetails. Attackers can iterate sequential integer user ids to harvest every user's email, name, avatar, currency, and bankingId and obapiProviderId open-banking identifiers.

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 oss-apps SplitPro 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?
