CVE-2024-47880: OpenRefine has a reflected cross-site scripting vulnerability from POST request in ExportRowsCommand

First published: Thu Oct 24 2024(Updated: )

### Summary The `export-rows` command can be used in such a way that it reflects part of the request verbatim, with a Content-Type header also taken from the request. An attacker could lead a user to a malicious page that submits a form POST that contains embedded JavaScript code. This code would then be included in the response, along with an attacker-controlled `Content-Type` header, and so potentially executed in the victim's browser as if it was part of OpenRefine. The attacker must know a valid project ID of a project that contains at least one row. ### Details The malicious form sets `contentType` to `text/html` (ExportRowsCommand.java line 101) and `preview` to `true` (line 107). This combination causes the browser to treat what OpenRefine thinks of as an export preview as a regular webpage. It would be safer if the `export-rows` command did not allow overriding the Content-Type header at all, instead relying on the exporter to provide the correct Content-Type. It could also require a CSRF token. As an additional measure, it could add a Content-Security-Policy header to the response disabling scripts and such entirely. At least the CSV exporter (`separator` and `lineSeparator` fields) and templating exporter (any field) are affected. It may also be possible to inject into the `dateSettings.custom` field or the SQL exporter default value field, if the project contains date or null cells. ### PoC An example form that demonstrates the issue is available on https://wandernauta.nl/os/. ### Impact Execution of arbitrary JavaScript in the user's browser. The attacker-provided code can do anything the user can do, including deleting projects, retrieving database passwords, or executing arbitrary Jython or Closure expressions, if those extensions are also present.
