# Oracle E-Business Suite: Installed Base flaw exposes critical data over HTTP

Oracle E-Business Suite's Installed Base module has a flaw in its Create Item Instance component that lets a low-privileged user reach the application over HTTP. A successful attack can read all Installed Base data and modify or delete some of it, and can affect other products in the suite.

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

## How to check

- Confirm the Oracle E-Business Suite release in use: unknown whether the sources list a version check command or file.
- Check whether Installed Base is in use in your E-Business Suite instance: unknown whether the sources give a setting to inspect.

## Fix

- Apply the Oracle Security Alert or Critical Patch Update that covers this CVE: unknown which patch number the sources name.
- Move to a fixed release of E-Business Suite 12.2: unknown which version the sources name as fixed.
