Funnelback patch

  • Released: 2018-11-05

  • Applies to: v15.0.0

  • Internal reference: FUN-12114, FUN-12116


Fixes security issues where:

  • The default form-not-found template reflected the given form id without proper escaping.

  • The default configuration of URL previewing could be used to expose local log file content.

Please ensure any custom form-not-found.ftl templates in collections are updated to perform correct escaping if they were derived from the previously vulnerable form-not-found.default.ftl.

Please ensure that any customized value for the global default_url_renderer.permitted_url_pattern setting in global.cfg prevents access to file:// URLs.

Affected files

  • web/templates/modernui/form-not-found.default.ftl

  • Deploy the provided files on top of an existing install (Note: No jetty restart is required for this change).

  • As patches are cumulative, apply deployment instructions from any previously unapplied patches.
