The vulnerability with CVE ID CVE-2024-23445 affects the API key based security model for remote clusters in ElasticSearch. It was discovered that if a cross-cluster API key restricts search for a specific index using the query or field_security parameter, and also grants replication for the same index, the search restrictions are not enforced during cross cluster search operations. This means that search results may include documents and terms that should not be returned. The vulnerability has a base severity of MEDIUM and a base score of 6.5 according to the CVSS version 3.1 scoring system. The risk score is 30, indicating a moderate level of risk. The vulnerability does not require high privileges or user interaction, and can be exploited via network attack vector. The confidentiality impact is high, while integrity impact is none and availability impact is also none. Remediation can be done by applying the necessary patches or updates provided by ElasticSearch to fix this vulnerability. Organizations using ElasticSearch in their infrastructure should take immediate action to prevent potential unauthorized access to sensitive data.
