CVE-2023-31417— Elasticsearch Insertion of sensitive information in audit logs

Quick assessment

Affected
Elastic Elasticsearch
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Elasticsearch是一个基于Lucene库的搜索引擎。 Elasticsearch 存在安全漏洞，该漏洞源于当对 Elasticsearch 的请求使用某些已弃用的 API URI 时，不会过滤掉敏感信息和凭证。可能导致密码和令牌等敏感信息可能会以明文形式打印在 Elasticsearch 审核日志中。

Vulnerability Title
Elasticsearch Insertion of sensitive information in audit logs
Source: CVE Program / CVE List V5
Vulnerability Description
Elasticsearch generally filters out sensitive information and credentials before logging to the audit log. It was found that this filtering was not applied when requests to Elasticsearch use certain deprecated URIs for APIs. The impact of this flaw is that sensitive information such as passwords and tokens might be printed in cleartext in Elasticsearch audit logs. Note that audit logging is disabled by default and needs to be explicitly enabled and even when audit logging is enabled, request bodies that could contain sensitive information are not printed to the audit log unless explicitly configured.
