Redcap Cross-site Scripting

A reflected XSS vulnerability exists in REDCap before 12.04.18 in the Alerts & Notifications upload feature. A crafted CSV file will, when uploaded, trigger arbitrary JavaScript code execution. (2022-10-12, CVE-2022-42715)

A Stored Cross-Site Scripting (XSS) vulnerability was discovered in Messenger/messenger_ajax.php in REDCap 12.0.11. This issue allows any authenticated user to inject arbitrary code into the messenger title (aka new_title) field when editing an existing conversation. The payload executes in the browser of any conversation participant with the sidebar shown. (2022-06-15, CVE-2022-24004)

A Stored Cross-Site Scripting (XSS) vulnerability was discovered in ProjectGeneral/edit_project_settings.php in REDCap 12.0.11. This issue allows any user with project management permissions to inject arbitrary code into the project title (app_title) field when editing an existing project. The payload is then reflected within the title tag of the page. (2022-06-15, CVE-2022-24127)

A stored Cross-Site Scripting (XSS) vulnerability in the Missing Data Codes functionality of REDCap before 11.4.0 allows remote attackers to execute JavaScript code in the client's browser by storing said code as a Missing Data Code value. This can then be leveraged to execute a Cross-Site Request Forgery attack to escalate privileges to administrator. (2022-04-13, CVE-2021-42136)

REDCap 10.3.4 contains a XSS vulnerability in the ToDoList function with parameter sort. The information submitted by the user is immediately returned in the response and not escaped leading to the reflected XSS vulnerability. Attackers can exploit vulnerabilities to steal login session information or borrow user rights to perform unauthorized acts. (2021-01-12, CVE-2020-26713)

A cross-site scripting (XSS) issue in REDCap 8.11.6 through 9.x before 10 allows attackers to inject arbitrary JavaScript or HTML in the Messenger feature. It was found that the filename of the image or file attached in a message could be used to perform this XSS attack. A user could craft a message and send it to anyone on the platform including admins. The XSS payload would execute on the other account without interaction from the user on several pages. (2020-11-02, CVE-2020-27359)

REDCap before 9.3.4 has XSS on the Customize & Manage Locking/E-signatures page via Lock Record Custom Text values. (2019-10-04, CVE-2019-17121)

REDCap before 9.3.0 allows XSS attacks against non-administrator accounts on the Data Import Tool page via a CSV data import file. (2019-08-21, CVE-2019-15127)

Multiple stored Cross-site scripting (XSS) issues in the admin panel and survey system in REDCap 8 before 8.10.20 and 9 before 9.1.2 allow an attacker to inject arbitrary malicious HTML or JavaScript code into a user's web browser. (2019-07-11, CVE-2019-13029)

Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.

The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:

https://server.com/confirmation?message=Transaction+Complete

what results in:

<span>Confirmation: Transaction Complete</span>

In that case the message can be modified to become a valid Javascript code, e.g.:

https://server.com/confirmation?message=<script>dangerous javascript code here</script>

and it will be executed locally by the user's browser with full access to the user's personal application/browser data:

<span>Confirmation: <script>dangerous javascript code here</script></span>
