Summary

A vulnerability in Apache Solr allows for potential remote code execution due to the improper handling of unauthenticated API uploads. Specifically, versions 6.6.0 to 6.6.6, 7.0.0 to 7.7.3, and 8.0.0 to 8.6.2 permit untrusted users to upload dangerous configurations through the ConfigSet API without proper authentication or authorization. Attackers can exploit this weakness by circumventing existing checks, enabling them to execute arbitrary code within the affected systems.

Affected Version(s)

Apache Solr Apache Solr 6.6.0 to 6.6.6, 7.0.0 to 7.7.3, 8.0.0 to 8.6.2
