CVE-2023-50386

Summary

CVE-2023-50386 is a vulnerability affecting Apache Solr versions 6.0.0 through 8.11.2, and 9.0.0 before 9.4.1. This issue involves improper control of dynamically-managed code resources, allowing for an unrestricted file upload with dangerous types. Specifically, the ConfigSets API accepted Java jar and class files, which, when saved during collection backups using the LocalFileSystemRepository, could be made available to any ConfigSet. If Solr was run in a secure manner with authorization enabled, this vulnerability was limited to extending backup permissions. Users are advised to upgrade to version 8.11.3 or 9.4.1, as these releases include protections that prevent the upload of executable files to configSets and restrict backup saving to non-ClassLoader directories.
