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

Published · Updated · NVD status: Analyzed

What it is

A file name from the request can climb out of the intended folder with sequences like ../, reaching files the service never meant to expose.

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 read or write files outside the folders the service meant to expose.

Is it being exploited?

There is no public report of exploitation yet.

What to do

  1. Upgrade IBM API Connect to a fixed version for your release line (10.0.8.13, 12.1.1.3). The patch notes are linked below.
  2. Until it is patched, review who holds accounts that can reach it.

Description from NVD

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to a path traversal vulnerability.

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

  • File storage the service can read or write. The flaw sits between the application and the file system it can reach.

Trust boundaries in play

  • Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
  • Between the application and the file system it can reach. An attacker who crosses it can read or write files outside the folders the service meant to expose.

Questions to answer about your own systems

  • Where does IBM API Connect 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?
