Overview

CVE-2023-50386 is a high-severity vulnerability. It was published on February 9, 2024 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Improper Control of Dynamically-Managed Code Resources, Unrestricted Upload of File with Dangerous Type, Inclusion of Functionality from Untrusted Control Sphere vulnerability in Apache Solr.This issue affects Apache Solr: from 6.0.0 through 8.11.2, from 9.0.0 before 9.4.1.

In the affected versions, Solr ConfigSets accepted Java jar and class files to be uploaded through the ConfigSets API.

When backing up Solr Collections, these configSet files would be saved to disk when using the LocalFileSystemRepository (the default for backups).

If the backup was saved to a directory that Solr uses in its ClassPath/ClassLoaders, then the jar and class files would be available to use with any ConfigSet, trusted or untrusted.

When Solr is run in a secure way (Authorization enabled), as is strongly suggested, this vulnerability is limited to extending the Backup permissions with the ability to add libraries.

Users are recommended to upgrade to version 8.11.3 or 9.4.1, which fix the issue.
