Quick assessment

Affected
Elastic Elastic Cloud Enterprise
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.

在 Elastic Cloud Enterprise（ECE）中存在“将敏感信息插入到外部可访问的文件或目录”（CWE-538）的漏洞，可能导致攻击者通过“检索嵌入的敏感数据”（CAPEC-37）获取凭证。ECE 将平台服务容器的运行时信息存储在一个权限较低的平台组件也可读取的位置，而这些信息包含了容器配置中的密钥。任何能够访问 ECE 内部平台服务的攻击者均可获取这些密钥，其中包括角色令牌（role tokens）。攻击者利用此类角色令牌，可以以该令牌所对应的角色权限，向安装环境中添加未经授权的宿主节点。

Vulnerability Title
Insertion of Sensitive Information into Externally-Accessible File or Directory in Elastic Cloud Enterprise (ECE) Leading to Credential Disclosure
Source: CVE Program / CVE List V5
Vulnerability Description
Insertion of Sensitive Information into Externally-Accessible File or Directory (CWE-538) in Elastic Cloud Enterprise (ECE) can lead to credential disclosure via Retrieve Embedded Sensitive Data (CAPEC-37). ECE stores runtime information about platform service containers in a location that lower-privileged platform components can read, and this information includes secrets from the container configuration. An attacker with access to the internal ECE platform services can obtain these secrets, which include role tokens. A role token can let the attacker add an unauthorized host to the installation with the roles of that token.
