Exploitation

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Netdata 是一款开源的可观测性工具。在版本 2.0.0 至 2.10.4 之间，Netdata Windows 代理程序的 MSI 安装修复功能会以提升的权限（即 SYSTEM 权限）在发起修复的用户桌面会话中交互式地启动 powershell.exe 和 wevtutil.exe。具有低权限的本地用户若触发修复操作，便可与这些可见进程窗口进行交互，或劫持这些窗口，从而以 SYSTEM 权限执行任意命令。该问题已在稳定版本 2.10.4 中得到修复。

Netdata: Local Privilege Escalation in Netdata Windows Agent installer via MSI Repair Execution

Source: CVE Program / CVE List V5

Vulnerability Description

Netdata is an open source observability tool. From version 2.0.0 until 2.10.4, Netdata Windows Agent MSI repair launches powershell.exe and wevtutil.exe as elevated interactive processes in the initiating user's desktop session. A low-privileged local user who triggers repair can interact with or hijack those visible process windows to execute arbitrary commands with SYSTEM privileges. This issue is fixed in stable version 2.10.4.
