Description

basic-ftp is an FTP client for Node.js. Versions prior to 5.3.0 are vulnerable to denial of service through unbounded memory growth while processing directory listings from a remote FTP server. A malicious or compromised server can send an extremely large or never-ending listing response to `Client.list()`, causing the client process to consume memory until it becomes unstable or crashes. Version 5.3.0 fixes the issue.

Weaknesses (CWE)

  • CWE-400 — Uncontrolled Resource Consumption (DoS)
  • CWE-770 — Allocation of Resources Without Limits or Throttling
