Technical ContextAI · show details
This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. vm2 is an open source vm/sandbox for Node.js. In vm2 for versions up to and including 3.9.19, Node.js custom inspect function allows attackers to escape the sandbox and run arbitrary code. This may result in Remote Code Execution, assuming the attacker has arbitrary code execution primitive inside the context of vm2 sandbox. There are no patches and no known workarounds. Users are advised to find an alternative software. Affected products include: Vm2 Project Vm2.

How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
OS command injection occurs when an application passes unsanitized user input directly into system shell commands.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
