SCA: security update for isolated-vm (GHSA-mmhj-4w6j-76h7)
critical Tenable Cloud Security Plugin ID 417037
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- isolated-vm is a library for nodejs which gives you access to v8's Isolate interface. Versions of
isolated-vm before v4.0.0 have API pitfalls which may make it easy for implementers to expose supposed
secure isolates to the permissions of the main nodejs isolate. Reference objects allow access to the
underlying reference's full prototype chain. In an environment where the implementer has exposed a
Reference instance to an attacker they would be able to use it to acquire a Reference to the nodejs
context's Function object. Similar application-specific attacks could be possible by modifying the local
prototype of other API objects. Access to NativeModule objects could allow an attacker to load and run
native code from anywhere on the filesystem. If combined with, for example, a file upload API this would
allow for arbitrary code execution. This is addressed in v4.0.0 through a series of related changes.
