Description

OpenRefine has a reflected cross-site scripting vulnerability (XSS) from POST request in ExportRowsCommand

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability none.

Weakness class

CVE-2024-47880 is classified as CWE-79: Cross-site Scripting (XSS). User-supplied data is written into a page without escaping, so attacker script runs in the browser of anyone who views it.
