https://notcve.org/view.php?id=CVE-2023-31418
An issue has been identified with how Elasticsearch handled incoming requests on the HTTP layer. An unauthenticated user could force an Elasticsearch node to exit with an OutOfMemory error by sending a moderate number of malformed HTTP requests. The issue was identified by Elastic Engineering and we have no indication that the issue is known or that it is being exploited in the wild. Se identificó un problema con la forma en que Elasticsearch manejó las solicitudes entrantes en la capa HTTP. Un usuario no autenticado podría forzar la salida de un nodo de Elasticsearch con un error OutOfMemory enviando una cantidad moderada de solicitudes HTTP con formato incorrecto. • https://discuss.elastic.co/t/elasticsearch-8-9-0-7-17-13-security-update/343616 https://security.netapp.com/advisory/ntap-20231130-0005 https://www.elastic.co/community/security • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2021-22147
Elasticsearch before 7.14.0 did not apply document and field level security to searchable snapshots. This could lead to an authenticated user gaining access to information that they are unauthorized to view. Elasticsearch versiones anteriores a 7.14.0, no aplicaba la seguridad a nivel de documento y de campo a las instantáneas con capacidad de búsqueda. Esto podía conllevar a que un usuario autenticado consiguiera acceso a información que no estaba autorizado a visualizar • https://discuss.elastic.co/t/elastic-stack-7-14-0-security-update/280344 https://security.netapp.com/advisory/ntap-20211008-0002 https://www.elastic.co/community/security • CWE-732: Incorrect Permission Assignment for Critical Resource CWE-862: Missing Authorization •

In Elasticsearch versions before 7.13.3 and 6.8.17 an uncontrolled recursion vulnerability that could lead to a denial of service attack was identified in the Elasticsearch Grok parser. A user with the ability to submit arbitrary queries to Elasticsearch could create a malicious Grok query that will crash the Elasticsearch node. En Elasticsearch versiones anteriores a 7.13.3 y la 6.8.17, se ha identificado una vulnerabilidad de recursión no controlada que podía conllevar a un ataque de denegación de servicio en el analizador Grok de Elasticsearch. Un usuario con la capacidad de enviar consultas arbitrarias a Elasticsearch podría crear una consulta Grok maliciosa que bloquearía el nodo de Elasticsearch • https://discuss.elastic.co/t/elasticsearch-7-13-3-and-6-8-17-security-update/278100 https://security.netapp.com/advisory/ntap-20210827-0006 https://www.oracle.com/security-alerts/cpuapr2022.html • CWE-674: Uncontrolled Recursion •

https://notcve.org/view.php?id=CVE-2021-22145
A memory disclosure vulnerability was identified in Elasticsearch 7.10.0 to 7.13.3 error reporting. A user with the ability to submit arbitrary queries to Elasticsearch could submit a malformed query that would result in an error message returned containing previously used portions of a data buffer. This buffer could contain sensitive information such as Elasticsearch documents or authentication details. Se ha identificado una vulnerabilidad de divulgación de memoria en los informes de errores de Elasticsearch versiones 7.10.0 hasta 7.13.3. Un usuario con la habilidad de enviar consultas arbitrarias a Elasticsearch podría enviar una consulta malformada que resultaría en un mensaje de error devuelto conteniendo porciones previamente usadas de un buffer de datos. • https://www.exploit-db.com/exploits/50149 https://github.com/niceeeeeeee/CVE-2021-22145-poc http://packetstormsecurity.com/files/163648/ElasticSearch-7.13.3-Memory-Disclosure.html https://discuss.elastic.co/t/elasticsearch-7-13-4-security-update/279177 https://security.netapp.com/advisory/ntap-20210827-0006 https://www.oracle.com/security-alerts/cpuapr2022.html • CWE-209: Generation of Error Message Containing Sensitive Information •
