Detailsinfo

A vulnerability, which was classified as problematic, has been found in Apache Solr up to 8.11.2/9.4.0. Affected by this issue is an unknown code. The manipulation with an unknown input leads to a dynamically-managed code resources vulnerability. Using CWE to declare the problem leads to CWE-913. The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements. The impact remains unknown. CVE summarizes:

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. In these versions, the following protections have been added: * Users are no longer able to upload files to a configSet that could be executed via a Java ClassLoader. * The Backup API restricts saving backups to directories that are used in the ClassLoader.

The weakness was shared 02/09/2024. The advisory is available at solr.apache.org. This vulnerability is handled as CVE-2023-50386 since 12/07/2023. The technical details are unknown and an exploit is not available.

Upgrading to version 9.4.1 eliminates this vulnerability.
