Descriptions

Improper Authentication vulnerability in Apache Solr.

Solr instances using the PKIAuthenticationPlugin, which is enabled by default when Solr Authentication is used, are vulnerable to Authentication bypass.
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.
This fake ending looks like an unprotected API path, however it is stripped off internally after authentication but before API routing.


This issue affects Apache Solr: from 5.3.0 before 8.11.4, from 9.0.0 before 9.7.0.

Users are recommended to upgrade to version 9.7.0, or 8.11.4, which fix the issue.

Vulnerabilidad de autenticación incorrecta en Apache Solr. Las instancias de Solr que utilizan PKIAuthenticationPlugin, que está habilitado de forma predeterminada cuando se utiliza la autenticación de Solr, son vulnerables a la omisión de la autenticación. Una terminación falsa al final de cualquier ruta de URL de la API de Solr permitirá que las solicitudes omitan la autenticación mientras se mantiene el contrato de API con la ruta de URL original. Esta terminación falsa parece una ruta de API desprotegida, sin embargo, se elimina internamente después de la autenticación pero antes del enrutamiento de API. Este problema afecta a Apache Solr: desde 5.3.0 hasta 8.11.4, desde 9.0.0 hasta 9.7.0. Se recomienda a los usuarios actualizar a la versión 9.7.0 o 8.11.4, que solucionan el problema.
