CWE ID 200


CVE-2023-50298 is a vulnerability in Apache Solr, affecting versions 6.0.0 through 8.11.2 and versions 9.0.0 before 9.4.1. The vulnerability allows an unauthorized actor to gain access to sensitive information by exploiting the Solr Streaming Expressions feature. By setting up a server to mimic ZooKeeper, the attacker can extract sensitive information by sending a streaming expression using the mock server's address in the "zkHost" parameter. To remediate this issue, users are advised to upgrade to version 8.11.3 or 9.4.1, which address the vulnerability by only using ZooKeeper credentials and ACLs for zkHost values with the same server address. This vulnerability poses a high danger to organizations as it allows unauthorized access to sensitive information, potentially leading to data breaches and compromising system security.
