Summary15672: LimeSurvey 3.21.1 Cross Site Scripting

Title: LimeSurvey 3.21.1 Cross Site Scripting (XSS) Stored

Date: 16/12/2019

Author: Guram Javakhishvili

Vendor Homepage:

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

Instance 1: - (Stored Cross Site Scripting XSS vulnerabilities)

The attacker needs the appropriate permissions in order to create new Attributes.
Then create an Attribute with a JavaScript payload in the Drop-down fields, for example:

Visit configurations > central participant database > Attributes.
Now create new Attributes. Fro attribute type, select Drop-down list and click add. Now insert below XSS payload into the field and click save. (Check first image below)


Once saved, now click edit (see second image).

Once the edit window opens it will be noted that the IFRAME has been created. When the attribute is being edited, e.g. by an administrative user, the JavaScript code will be executed in the browser. See third image below.

Additional Information

Vulnerable parameter: ParticipantAttributeNamesDropdown[]
Attack vector: test<input><svg+"/onmouseover="confirm('AttDropdown');//"onload=onload>so5cx\\"onmouseover=alert('AttDropdown');//><iframe/onmouseover=alert('AttDropdown')></iframe>//
