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 •

All versions of Elastic Cloud Enterprise has the Elasticsearch “anonymous” user enabled by default in deployed clusters. While in the default setting the anonymous user has no permissions and is unable to successfully query any Elasticsearch APIs, an attacker could leverage the anonymous user to gain insight into certain details of a deployed cluster. Todas las versiones de Elastic Cloud Enterprise presentan el usuario "anonymous" de Elasticsearch habilitado por defecto en los clusters desplegados. Mientras que en la configuración por defecto el usuario anónimo no presenta permisos y no puede consultar con éxito cualquier API de Elasticsearch, un atacante podría aprovechar el usuario anónimo para conseguir información sobre determinados detalles de un clúster desplegado • https://www.exploit-db.com/exploits/50152 http://packetstormsecurity.com/files/163655/Elasticsearch-ECE-7.13.3-Database-Disclosure.html https://discuss.elastic.co/t/elastic-cloud-enterprise-security-update/279180 https://security.netapp.com/advisory/ntap-20210819-0005 •

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 •

Elasticsearch versions before 7.11.2 and 6.8.15 contain a document disclosure flaw was found in the Elasticsearch suggester and profile API when Document and Field Level Security are enabled. The suggester and profile API are normally disabled for an index when document level security is enabled on the index. Certain queries are able to enable the profiler and suggester which could lead to disclosing the existence of documents and fields the attacker should not be able to view. Elasticsearch versiones anteriores a 7.11.2 y 6.8.15, contienen un fallo en la divulgación de documentos que se encontró en la API suggester y profile de Elasticsearch cuando Document and Field Level Security está habilitada. La API suggester y profile normalmente están deshabilitadas para un índice cuando la seguridad a nivel de documento está habilitada en el índice. • 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-2021-22135 https://bugzilla.redhat.com/show_bug.cgi?id=1943184 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
