Summary
Indico Affected by Cross-Site-Scripting via material uploads
Details

Impact

There is a Cross-Site-Scripting vulnerability when uploading certain file types as materials.

Patches

You should to update to Indico 3.3.10 as soon as possible. See the docs for instructions on how to update.

Please be aware that to apply the fix itself updating is sufficient, but to benefit from the strict Content-Security-Policy we now apply by default for file downloads, you need to update your webserver config in case you use nginx with Indico's STATIC_FILE_METHOD set to xaccelredirect and add the following line to the .xsf/indico/ location block (you can consult the Indico setup documentation for the full configuration snippet):

add_header Content-Security-Policy $upstream_http_content_security_policy;

Workarounds

  • Use your webserver config to apply a strict CSP for material download endpoints.
  • Only let trustworthy users create content (including material uploads, which speakers can typically do as well) on Indico.
