Apache Solr 6.6.x < 6.6.7 / 7.x < 7.7.4 / 8.x < 8.6.3 Authentication Bypass (CVE-2020-13957)

critical Nessus Plugin ID 181480

Synopsis

The remote web server contains a Java application that is affected by an authentication bypass vulnerability.

Description

The version of Apache Solr running on the remote host is 6.6.x prior to 6.6.7, or 7.x prior to 7.7.4, or 8.x prior to 8.6.3. It is, therefore, affected by an authentication bypass vulnerability. Apache Solr prevents some features considered dangerous (which could be used for remote code execution) to be configured in a ConfigSet that's uploaded via API without authentication/authorization. The checks in place to prevent such features can be circumvented by using a combination of UPLOAD/CREATE actions.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Solr version 8.6.3 or later, or apply any of the mitigations provided in the vendor's advisory.
