Description

Improper Authentication vulnerability in Apache Solr.<br /> <br /> Solr instances using the PKIAuthenticationPlugin, which is enabled by default when Solr Authentication is used, are vulnerable to Authentication bypass.<br /> A fake ending at the end of any Solr API URL path, will allow requests to skip Authentication while maintaining the API contract with the original URL Path.<br /> This fake ending looks like an unprotected API path, however it is stripped off internally after authentication but before API routing.<br /> <br /> <br /> This issue affects Apache Solr: from 5.3.0 before 8.11.4, from 9.0.0 before 9.7.0.<br /> <br /> Users are recommended to upgrade to version 9.7.0, or 8.11.4, which fix the issue.
