利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
以下是该漏洞描述的中文翻译： 描述 当配置了 ZooKeeper 认证时，Apache Storm 会刻意在拓扑配置中保留 ，因为 Worker 节点需要它。Nimbus 随后会将该配置原样发送给任何拥有只读拓扑权限的调用者，这意味着一个仅拥有查看拓扑权限的用户也能获取到该 ZooKeeper 凭据。 该凭据并非只读。集群状态实现使用具有写权限的 ACL（访问控制列表）用于 Worker 心跳、背压机制和错误状态，因此接收到该凭据的用户可以伪造或删除相应拓扑的集群状态。需要注意的是，该凭据并非用于分配（assign

Vulnerability Title
Apache Storm Nimbus, Apache Storm Client: Disclosure of the Topology ZooKeeper Credential to Read-Only Users and to Logs
来源: CVE Program / CVE List V5
Vulnerability Description
Description
When ZooKeeper authentication is configured, Storm deliberately retains
`storm.zookeeper.topology.auth.payload` in the topology configuration, because workers need it. Nimbus then
served that configuration verbatim to any caller holding read-only topology permissions, so a user whose
only grant was the ability to view a topology received its ZooKeeper credential.
That credential is not read-only. The cluster state implementation uses write-capable ACLs for worker
heartbeats, backpressure and error state, so a recipient can forge or remove that state for the topology
concerned. It is not a write credential on assignments.
The same advisory covers the submission client, which logged the generated payload at INFO on every
submission that generated one, and the SASL handlers, which logged it at DEBUG. The credential therefore
also reached any log aggregation or support bundle collected from the cluster.
Mitigation
Upgrade to 3.1.0, where the payload is removed from the configuration served to read-only callers and is no
longer written to logs.
Users who cannot upgrade immediately should rotate `storm.zookeeper.topology.auth.payload` for existing
topologies, review retained logs and support bundles for the value, and restrict read-only topology
permissions to trusted principals.
