Linux Distros Unpatched Vulnerability : CVE-2026-22022

high Nessus Plugin ID 297709

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.

 - Deployments of Apache Solr 5.3.0 through 9.10.0 that rely on Solr's Rule Based Authorization Plugin are vulnerable to allowing unauthorized access to certain Solr APIs, due to insufficiently strict input validation in those components. Only deployments that meet all of the following criteria are impacted by this vulnerability: * Use of Solr's RuleBasedAuthorizationPlugin * A RuleBasedAuthorizationPlugin config (see security.json) that specifies multiple roles * A RuleBasedAuthorizationPlugin permission list (see security.json) that uses one or more of the following pre-defined permission rules: config-read, config-edit, schema-read, metrics-read, or security-read. * A RuleBasedAuthorizationPlugin permission list that doesn't define the all pre-defined permission * A networking setup that allows clients to make unfiltered network requests to Solr. (i.e. user-submitted HTTP/HTTPS requests reach Solr as-is, unmodified or restricted by any intervening proxy or gateway) Users can mitigate this vulnerability by ensuring that their RuleBasedAuthorizationPlugin configuration specifies the all pre-defined permission and associates the permission with an admin or other privileged role. Users can also upgrade to a Solr version outside of the impacted range, such as the recently released Solr 9.10.1.
 (CVE-2026-22022)

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