Server-Side Request Forgery (SSRF) in ip

CVE-2023-42282

  • ip
  • org.webjars.npm:ip
High
9.8/10

Summary

The `isPublic()` function in the NPM package ip doesn't correctly identify certain private IP addresses in uncommon formats, such as 0x7F.1 as private. Instead, it reports them as public by returning true. This can lead to security issues such as Server-Side Request Forgery (SSRF) if `isPublic()` is used to protect sensitive code paths when passed user input. Versions prior to 1.1.9 and versions 2.x prior to 2.0.1 are affected.

CWE-918 - Server-Side Request Forgery (SSRF)

Server-side request forgery (SSRF) is a weakness that allows an attacker to send an arbitrary request, making it appear that the request was sent by the server. This request may bypass a firewall that would normally prevent direct access to the URL. The impact of this vulnerability can vary from unauthorized access to files and sensitive information to remote code execution.
