# Oracle E-Business Suite Marketing Audience: flaw lets low-privilege users read and change data

Oracle Marketing, part of Oracle E-Business Suite, has a flaw in its Audience component affecting versions 12.2.3 through 12.2.15. An attacker with a low-privilege account over HTTP can read a subset of Marketing data and modify or delete some of it, provided a person other than the attacker takes an action.

_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, and whether the Marketing module is installed, with the E-Business Suite version shown in the Oracle EBS admin pages
- Check whether the installed Marketing release falls within 12.2.3 to 12.2.15 against the Oracle Critical Patch Update advisory
- unknown for the exact check command or file, the sources do not say

## Fix

- Apply the Oracle Critical Patch Update that covers the Oracle Marketing Audience component for E-Business Suite 12.2.x
