제출 #628437: Scada-LTS 2.7.8.1 Cross Site Scripting

Multiples Stored Cross-Site Scripting (XSS) in mailing_lists.shtm

Summary

Multiples Stored Cross-Site Scripting (XSS) vulnerability was identified in the mailing_lists.shtm endpoint of the Scada-LTS application. This vulnerability allows attackers to inject malicious scripts into the name, userList and address parameters. The injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk.

Details

Vulnerable Endpoint: mailing_lists.shtm

Parameters: name,userList and address

The application fails to properly validate and sanitize user inputs in the name, userList and address parameters. This lack of validation allows attackers to inject malicious scripts, which are then stored on the server. Whenever the affected page is accessed, the malicious payload is executed in the victim's browser, potentially compromising the user's data and system.

PoC

Step by Step:

Access vulnerable endpoint, insert the payload in second field ("Name").

Note: As admin, you can add a test user in users.shtm page with the same payload, select the test user (named with the paylod) and click on "+" to add the xss in third field ("Add user") (Steps 2 and 3). The payload will be activated automatically.

Insert the paylod in fourth field ("Add address"), click on "+" to add. The payload will be activated automatically. Then, click on "disk" to save and the payloads will be activated automatically.
