# Oracle E-Business Suite Capacity: low-privilege HTTP access exposes critical data

Oracle Capacity, a module of Oracle E-Business Suite 12.2.3 through 12.2.15, has a flaw in its Internal Operations component. A low-privileged user who can reach it over HTTP can read critical data, change or delete some records, and partly disrupt the service.

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

## How to check

- Confirm the Oracle Capacity module is installed in E-Business Suite and note the release, for example with `unknown` from the sources
- Check the E-Business Suite release level against `12.2.3` through `12.2.15`

## Fix

- Apply the Oracle Critical Patch Update fix for Oracle E-Business Suite Capacity; the specific patch is unknown from the sources
- Restrict HTTP access to the Capacity pages to trusted internal users until patched
