Linux Distros Unpatched Vulnerability : CVE-2023-50291

high Nessus Plugin ID 250332

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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).*' (CVE-2023-50291)

Note that Nessus relies on the presence of the package as reported by the vendor.
