Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: vm2 < 3.9.15 fails to handle unhandled async errors correctly when passing host objects. ๐ **Consequences**: Attackers can bypass the sandbox protection entirely, leading to Remote Code Execution (RCE).โฆ
๐ฆ **Affected**: **vm2** (Node.js advanced VM/Sandbox). ๐ค **Vendor**: Patrik Simek. ๐ **Version**: All versions **prior to 3.9.15**. If you are using an older version, you are vulnerable.
Q4What can hackers do? (Privileges/Data)
๐ป **Capabilities**: Full **Remote Code Execution (RCE)**. ๐ **Impact**: High. CVSS Score indicates Critical impact on Confidentiality, Integrity, and Availability.โฆ
๐ **Exploit Status**: **YES**. Public PoCs and reverse shell exploits are available on GitHub (e.g., `CVE-2023-29017-reverse-shell`). Wild exploitation is highly likely given the ease of access.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: 1. Check `package.json` for `vm2` version. 2. If version < 3.9.15, you are at risk. 3. Scan for usage of `vm2` in your codebase. 4. Look for unhandled async errors in sandboxed code execution paths.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fix**: **YES**. Official patch released in **version 3.9.15**. ๐ **Commit**: d534e5785f38307b70d3aac1945260a261a94d50. Update immediately to the latest safe version.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If you cannot upgrade immediately: 1. **Avoid** passing complex host objects into the VM. 2. Ensure all async operations inside the VM have robust **error handling** and rejection handlers. 3.โฆ
๐ฅ **Priority**: **CRITICAL / URGENT**. With CVSS High severity, no auth required, and public exploits, this must be patched **immediately**. Do not wait. Update to vm2 >= 3.9.15 now.
