CVE-2020-8129Public exploitNetwork attack vector

Unauthenticated code execution via unvalidated module path

Published Feb 14, 2020 · Updated Aug 4, 2024

Code injection in Pofider script-manager 0.8.6 and earlier allows remote attackers to execute arbitrary code through a worker HTTP server. In lib/worker-servers.js, processRequest accepts direct HTTP messages and loads req.body.options.execModulePath with require() without authenticating the request. Network access to the dynamically chosen worker port and knowledge of that port are required; the default host setting is 127.0.0.1.
