Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: VM2 (Node.js sandbox) has a **Sandbox Escape** flaw. <br>๐ฅ **Consequences**: Attackers break out of the isolated VM environment. <br>โ ๏ธ **Impact**: Arbitrary command execution on the **host system**.โฆ
๐ก๏ธ **CWE**: CWE-94 (Code Injection). <br>๐ **Flaw**: Improper neutralization of special elements in code. <br>๐ **Root**: The sandbox mechanism fails to restrict specific code patterns, allowing host-level access.
Q3Who is affected? (Versions/Components)
๐ฆ **Product**: `vm2` by `patriksimek`. <br>๐ **Affected**: Versions **< 3.11.0**. <br>๐ **Context**: Any Node.js app using VM2 for untrusted code execution is at risk.
Q4What can hackers do? (Privileges/Data)
๐ **Privileges**: **Host System** access. <br>๐พ **Data**: Full read/write access to host files. <br>๐ **Action**: Execute **arbitrary commands** (RCE).โฆ
๐ช **Auth**: None required (PR:N). <br>๐ **Network**: Remote (AV:N). <br>๐ฏ **Complexity**: Low (AC:L). <br>๐ค **UI**: None needed (UI:N). <br>โ **Threshold**: **Very Low**. Easy to exploit if VM2 is exposed.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exploit**: No specific PoC code in data (pocs: []). <br>๐ **Advisory**: Confirmed via GitHub Security Advisory (GHSA-grj5-jjm8-h35p).โฆ
๐ **Check**: Scan for `vm2` dependency in `package.json`. <br>๐ **Version**: Verify version is **< 3.11.0**. <br>๐ ๏ธ **Tool**: Use SCA tools to detect vulnerable `vm2` packages in your project.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: Yes. <br>๐ง **Patch**: Upgrade to **v3.11.0** or later. <br>๐ **Source**: See GitHub Release v3.11.0 and commit f9b700b1c7d9. <br>๐ **Status**: Officially resolved.
Q9What if no patch? (Workaround)
๐ซ **No Patch?**: **Stop using VM2** for untrusted input. <br>๐ **Alternative**: Use `isolated-vm` or Node.js `Worker Threads` (more secure). <br>๐ก๏ธ **Mitigation**: Run in restricted containers with minimal privileges.
