# Oracle E-Business Suite Capacity: low-privilege HTTP attacker reads and changes 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 with network access over HTTP can read critical data, change or delete some records, and cause a partial denial of service.

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

## How to check

- Check the installed Oracle E-Business Suite release and whether the Capacity module is in use; the sources do not give a command for this.
- Confirm whether `12.2.3` through `12.2.15` are in use, as stated in the advisory text.

## Fix

- Apply the Oracle Critical Patch Update fix for Oracle E-Business Suite Capacity; the sources do not name the patch or the target version.
