Vulnerability from cnvd - Published: 2021-02-22

Title

Apache Cassandra信息泄露漏洞

Description

Apache Cassandra是Apache基金会的一个分布式Nosql数据库。Cassandra是一个混合型的非关系的数据库，类似于Google的BigTable。其主要功能比Dynamo （分布式的Key-Value存储系统）更丰富，但支持度却不如文档存储MongoDB（介于关系数据库和非关系数据库之间的开源产品，是非关系数据库当中功能最丰富，最像关系数据库的。 Cassandra 2.1.0至2.1.22、2.2.0至2.2.19、3.0.0至3.0.23和3.11.0至3.11.9存在安全漏洞，在使用“dc”或“rack”节间加密设置时，允许加密和未加密的节间连接。配置错误的节点或恶意用户可以使用未加密的连接，尽管不在同一机架或dc中，并绕过相互TLS要求。目前没有详细漏洞细节提供。

CVE-2020-17516 (GCVE-0-2020-17516)

Vulnerability from cvelistv5 – Published: 2021-02-03 16:40 – Updated: 2024-08-04 14:00

Summary

Apache Cassandra versions 2.1.0 to 2.1.22, 2.2.0 to 2.2.19, 3.0.0 to 3.0.23, and 3.11.0 to 3.11.9, when using 'dc' or 'rack' internode_encryption setting, allows both encrypted and unencrypted internode connections. A misconfigured node or a malicious user can use the unencrypted connection despite not being in the same rack or dc, and bypass mutual TLS requirement.

Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
