CVE-2023-50291

Insufficiently Protected Credentials vulnerability in Apache Solr. This
issue affects Apache Solr: from 6.0.0 through 8.11.2, from 9.0.0 before
9.3.0. One of the two endpoints that publishes the Solr process’ Java
system properties, /admin/info/properties, was only setup to hide system
properties that had “password” contained in the name. There are a number of
sensitive system properties, such as “basicauth” and “aws.secretKey” do not
contain “password”, thus their values were published via the
“/admin/info/properties” endpoint. This endpoint populates the list of
System Properties on the home screen of the Solr Admin page, making the
exposed credentials visible in the UI. This /admin/info/properties endpoint
is protected under the “config-read” permission. Therefore, Solr Clouds
with Authorization enabled will only be vulnerable through logged-in users
that have the “config-read” permission. Users are recommended to upgrade to
version 9.3.0 or 8.11.3, which fixes the issue. A single option now
controls hiding Java system property for all endpoints,
“-Dsolr.hiddenSysProps”. By default all known sensitive properties are
hidden (including “-Dbasicauth”), as well as any property with a name
containing “secret” or “password”. Users who cannot upgrade can also use
the following Java system property to fix the issue:
‘-Dsolr.redaction.system.pattern=.(password|secret|basicauth).’
