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-2021-22144
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 •
CVSS: 5.3EPSS: 0%CPEs: 2EXPL: 0CVE-2021-22137 – elasticsearch: Document disclosure flaw when Document or Field Level Security is used
https://notcve.org/view.php?id=CVE-2021-22137
In Elasticsearch versions before 7.11.2 and 6.8.15 a document disclosure flaw was found when Document or Field Level Security is used. Search queries do not properly preserve security permissions when executing certain cross-cluster search queries. This could result in the search disclosing the existence of documents the attacker should not be able to view. This could result in an attacker gaining additional insight into potentially sensitive indices. En Elasticsearch versiones anteriores a 7.11.2 y la 6.8.15, se encontró un fallo en la divulgación del documento cuando Document o Field Level Security es usado. • https://discuss.elastic.co/t/elastic-stack-7-12-0-and-6-8-15-security-update/268125 https://security.netapp.com/advisory/ntap-20210625-0003 https://access.redhat.com/security/cve/CVE-2021-22137 https://bugzilla.redhat.com/show_bug.cgi?id=1943189 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-281: Improper Preservation of Permissions •
