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).
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
