# Oracle SOA Suite Fabric Layer flaw lets low-privileged users change data over HTTP

Oracle SOA Suite's Fabric Layer component has a flaw that lets a low-privileged user reach it over HTTP. A successful attack can create, delete or modify data the suite can access and partly disrupt the service.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether Oracle SOA Suite is installed and which version runs, for example in the Fusion Middleware console or the SOA server home.
- Confirm whether the installed version is `12.2.1.4.0` or `14.1.2.0.0`.

## Fix

- Move Oracle SOA Suite to a patched release from Oracle's Critical Patch Update for the affected line (the sources do not name the fixed build: unknown).
