| Mô tả | # Cross-Site Scripting (XSS) Stored endpoint `watch_list.shtm` parameter `name`
---
## Summary
A Stored Cross-Site Scripting (XSS) vulnerability was identified in the `watch_list.shtm` endpoint of the _SCADA-LTS_ application. This vulnerability allows attackers to inject malicious scripts into the `name` parameter. The injected payload is stored on the server and executed automatically in the browser of any user who accesses the affected data source entry, creating a persistent attack vector.
---
## Details
**Vulnerable Endpoint:** `POST /watch_list.shtm`
**Parameter:** `name`
The application does not properly validate or sanitize input in the `name` field. As a result, an attacker can inject JavaScript code, which is stored in the system and later rendered in the application’s interface, leading to automatic execution in the user's browser.

## PoC
**Payload:**
`<img src=x onerror=alert("Watchlist")>`
### Steps to Reproduce:
1. Log in to the _SCADA-LTS_ application with an account that has permission to create or edit Watchlists.
2. Navigate to the pencil button on the top right of the application to add/edit a watchlist .
3. ClickIn the **Name** field, insert the payload:
`<img src=x onerror=alert("Watchlist")>`
4. Fill in any other required fields and click **Save**.

## Impact
Stored XSS attacks can lead to severe consequences, including:
- **Session hijacking:** Stealing cookies or authentication tokens to impersonate users
- **Credential theft:** Capturing usernames and passwords through malicious scripts
- **Malware delivery:** Distributing harmful code to application users
- **Privilege escalation:** Compromising higher-privilege accounts via persistent scripts
- **Data manipulation or defacement:** Altering displayed content in the application
- **Reputation damage:** Eroding trust among system users and stakeholders |
