## Overview

OCS Inventory NG Server version 2.12.3 and prior contain a stored cross-site scripting vulnerability that allows unauthenticated attackers to execute arbitrary JavaScript by submitting malicious User-Agent HTTP headers to the /ocsinventory endpoint. Attackers can register rogue agents or craft requests with malicious User-Agent values that are stored without sanitization and rendered with insufficient encoding in the web console, leading to arbitrary JavaScript execution in the browsers of authenticated users viewing the statistics dashboard.

## Affected

- `ng_server <= 2.12.3`
