Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: VM2 (Node.js sandbox) has a **Sandbox Escape** via the `inspect` method. π **Consequences**: Attackers break out of the isolated environment to execute **arbitrary commands** on the host system.β¦
π‘οΈ **CWE-94**: Improper Control of Generation of Code (Code Injection). π **Flaw**: The `inspect` function is not properly sanitized, allowing malicious code to bypass VM2's security boundaries.
Q3Who is affected? (Versions/Components)
π¦ **Product**: `vm2` by `patriksimek`. π **Affected**: Versions **prior to 3.11.0**. If you are using v3.10.x or lower, you are at risk!
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Full Host System Access. πΎ **Data**: Complete Read/Write/Execute capabilities on the server. Hackers can run **any command** as the Node.js process user.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: LOW. π **Network**: Remote (AV:N). π **Auth**: None required (PR:N). π±οΈ **UI**: None required (UI:N). Easy to exploit if the library is used to process untrusted input.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: No specific PoC code provided in the data. π **Status**: Advisory confirmed (GHSA-v37h-5mfm-c47c). High risk of wild exploitation due to low complexity.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for `vm2` dependency in `package.json`. π **Version**: Ensure version is **< 3.11.0**. π« **Feature**: Check if you use `vm2` to sandbox untrusted user code.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: YES! π οΈ **Patch**: Upgrade to **v3.11.0** or later. π **Ref**: See GitHub Advisory and Release v3.11.0 for details.
Q9What if no patch? (Workaround)
π§ **Workaround**: If you cannot upgrade immediately, **disable the `inspect` method** in the VM2 configuration. π« **Best Practice**: Avoid using `vm2` for untrusted code until patched.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: CRITICAL. π **CVSS**: 9.8 (High). β‘ **Action**: Patch immediately! This is a remote code execution vulnerability with no authentication needed.
