CVE-2020-7678Public exploitNetwork attack vector

Arbitrary code execution via unsanitized eval

Published Jul 25, 2022 · Updated Sep 17, 2024

Code injection in node-import 0.9.2 and earlier allows remote attackers to execute arbitrary JavaScript via crafted module parameters. The Imports.module function concatenates each unsanitized params property name into a variable declaration passed to eval in index.js. Exploitation requires a consuming application to pass attacker-controlled property names to that API; successful code runs with the Node.js process's privileges.
