Quick assessment

Affected
Red Hat Assisted Installer for Red Hat OpenShift Container Platform 2
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 oc-mirror 中发现了一个漏洞。在执行镜像同步操作期间，内置的本地缓存注册表未进行身份验证或加密，而是绑定到所有网络接口，而非仅限于本地系统访问。相邻网络上的未认证攻击者可以连接到该暴露的服务，从而推送被篡改的容器镜像、删除已缓存的镜像或访问已同步的内容。

Vulnerability Title
Oc-mirror__release-4.21: embedded local cache registry listens on all interfaces without authentication, with delete enabled
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in oc-mirror. During mirroring operations, the embedded local cache registry binds to all network interfaces without authentication or encryption instead of restricting access to the local system. An unauthenticated attacker on an adjacent network can connect to the exposed service to push tampered container images, delete cached images, or access mirrored content.
