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。
漏洞描述 Logviewer 提供了 和 配置项，以便操作员可以控制谁有权读取日志内容。但对于守护进程（daemon）日志，这些设置并未生效：访问控制逻辑将“这是守护进程日志”标志与授权器（authorizer）的结果结合时，只要该标志被设置，授权器的判断结果就会被丢弃；并且，守护进程日志页面及下载端点在到达处理程序（handler）时，完全没有咨询授权器。因此，任何能够通过已配置的 Servlet 过滤器的用户，都能在每一个可达节点上读取 、 以及其他守护进程日志，其中包含其他租户的拓扑名称、所有者以及配置片段。

Vulnerability Title
Apache Storm Logviewer: Log Access Controls Not Enforced by Logviewer
来源: CVE Program / CVE List V5
Vulnerability Description
Description
The Logviewer offers `logs.users` and `logs.groups` so operators can control who may read log content. For
daemon logs those settings were not applied: the access decision combined the "this is a daemon log" flag
with the authorizer result in a way that discarded the authorizer's answer whenever the flag was set, and
the daemon log page and download endpoints reached the handler without consulting an authorizer at all. Any
user able to pass the configured servlet filter could therefore read `nimbus.log`, `supervisor.log` and the
other daemon logs on every reachable node, which contain other tenants' topology names, owners and
configuration fragments.
The same advisory covers the log listing endpoints, which accepted a user argument and never applied it, so
`/listLogs` and `/searchLogs` returned every tenant's topology and worker log file names regardless of the
caller. That part is metadata only.
There was no configuration that closed either behaviour.
Mitigation
Upgrade to 3.1.0, where the daemon log paths evaluate the same configured user and group lists that the
worker log paths already used, and the listing endpoints filter by the requesting user.
Users who cannot upgrade immediately should place the Logviewer behind a reverse proxy that restricts the
daemon log endpoints, and should treat daemon log content as readable by any filter-authenticated user.
