CVE-2022-23812

RIAEvangelist/node-ipc 是恶意软件/抗议软件

RIAEvangelist/node-ipc 模块包含抗议软件 peacenotwar。

来自 RIAEvangelist/node-ipc 的摘录：

自 v11.0.0 和 v9.2.2 起，此模块使用了 peacenotwar 模块。

更重要的是，RIAEvangelist/node-ipc 的提交 847047cf7f81ab08352038b2204f0e7633449580 -> 6e344066a0464814a27fbd7ca8422f473956a803 包含恶意软件。

我反混淆了上面的代码，发现如果宿主机的公网 IP 地址来自俄罗斯或白俄罗斯， node-ipc 会递归地向上遍历父目录，用爱心 emoji 覆盖许多文件：

我只是让危险代码更好看并加了注释，方便你们尝试。显然，这段代码会删除你驱动器上几乎所有内容。

可用的缓解方法：

以下缓解策略受 cnpm（不是 npm）的缓解方法启发： https://github.com/cnpm/bug-versions/pull/181

如果你使用以下缓解策略之一，请确保移除 ^ 以强制 node-ipc 使用指定版本。

"^9.x.x" -> "9.2.1"

     "dependencies": {
-        "node-ipc": "^9.x.x"
+        "node-ipc": "9.2.1"
     }

"^10.x.x" -> "10.1.0"

     "dependencies": {
-        "node-ipc": "^10.x.x"
+        "node-ipc": "10.1.0"
     }

"^11.x.x" -> "10.1.0"

     "dependencies": {
