Server-Side Request Forgery in private-ip

Critical severity GitHub Reviewed Published Apr 13, 2021 to the GitHub Advisory Database • Updated Feb 1, 2023

Package

npm private-ip (npm)

Affected versions

< 2.0.0

Patched versions

2.0.0

Description

Insufficient RegEx in private-ip npm package v1.0.5 and below insufficiently filters reserved IP ranges resulting in indeterminate SSRF. An attacker can perform a large range of requests to ARIN reserved IP ranges, resulting in an indeterminable number of critical attack vectors, allowing remote attackers to request server-side resources or potentially execute arbitrary code through various SSRF techniques.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
