| 标题 | Scada-LTS 2.7.8.1 Cross Site Scripting (XSS) Stored |
|---|
| 描述 | # Cross-Site Scripting (XSS) Stored endpoint `compound_events.shtm` parameter `name`
---
## Summary
A Stored Cross-Site Scripting (XSS) vulnerability was identified in the `compound_events.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 compound event entry, creating a persistent attack vector.
---
## Details
**Vulnerable Endpoint:** `POST /compound_events.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, causing automatic execution in the user's browser.
---
## PoC
**Payload:**
`<img src=x onerror=alert('Compound-PoC-XSS')>`
### Steps to Reproduce:
1. Log in to the _SCADA-LTS_ application with an account that has permission to create or edit compound events.
2. Navigate to the **Compound Events** section and select **Add Compound Event** or edit an existing entry.
3. In the **Name** field, insert the payload above:
`<img src=x onerror=alert('Compound-PoC-XSS')>`
4. Complete any 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 |
