CVE-2025-66030: Medium Severity Vulnerability in node-forge-0.10.0

Hey guys! Let's dive into a critical security issue that you need to be aware of if you're using node-forge. This article breaks down CVE-2025-66030, a medium severity vulnerability detected in node-forge-0.10.0.tgz. We'll cover what the vulnerability is, its potential impact, and, most importantly, how to fix it.

Vulnerable Library: node-forge-0.10.0.tgz

What is node-forge?

Node-forge, also known as Forge, is a comprehensive JavaScript library that provides native implementations for various network transports, cryptographic algorithms, ciphers, Public Key Infrastructure (PKI), message digests, and other essential utilities. It's a powerful tool for developers needing robust security features directly in their JavaScript applications. Because of its widespread use, any vulnerability within node-forge can have significant implications.

Description: JavaScript implementations of network transports, cryptography, ciphers, PKI, message digests, and various utilities.

Found in Base Branch: master

Understanding the Vulnerability

The identified vulnerability, CVE-2025-66030, is an Integer Overflow. Specifically, versions 1.3.1 and below of node-forge contain a flaw that allows remote, unauthenticated attackers to craft specially designed ASN.1 structures. These structures include Object Identifiers (OIDs) with arcs that are excessively large. Due to a 32-bit bitwise truncation during decoding, these oversized arcs can be misinterpreted as smaller, trusted OIDs. This misinterpretation can lead to a bypass of security decisions that rely on OID validation, potentially compromising the integrity and security of the application.

ASN.1 (Abstract Syntax Notation One) is a standard interface description language for defining data structures used in telecommunications and computer networking. OIDs are used to uniquely identify objects in ASN.1 structures. The vulnerability stems from how node-forge handles these OIDs, making it possible for attackers to manipulate them in a way that subverts security measures.

This type of vulnerability is particularly concerning because it can be exploited remotely without requiring any authentication. An attacker can simply send a crafted ASN.1 structure to a vulnerable application and potentially gain unauthorized access or control.

CVSS 3 Score Details (5.3)

The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of security vulnerabilities. The CVSS 3 score for CVE-2025-66030 is 5.3, which is classified as a medium severity vulnerability. Let's break down the components of this score:

Base Score Metrics:
- Exploitability Metrics:
  - Attack Vector: Network (AV:N) - The vulnerability can be exploited over a network.
  - Attack Complexity: Low (AC:L) - The vulnerability is easy to exploit.
  - Privileges Required: None (PR:N) - No privileges are required to exploit the vulnerability.
  - User Interaction: None (UI:N) - No user interaction is required to exploit the vulnerability.
  - Scope: Unchanged (S:U) - An exploited vulnerability can only affect resources managed by the same security authority.
- Impact Metrics:
  - Confidentiality Impact: None (C:N) - There is no impact on confidentiality.
  - Integrity Impact: Low (I:L) - There is a low impact on integrity, meaning that the attacker can modify data, but the scope of the modification is limited.
  - Availability Impact: None (A:N) - There is no impact on availability.

The CVSS score reflects that while the vulnerability is easily exploitable over a network without any required privileges or user interaction, the primary impact is on integrity, with no impact on confidentiality or availability. This means an attacker could potentially modify data, but the extent of the modification is limited. For a more detailed understanding of CVSS3 Scores, you can refer to the CVSS Calculator.

Suggested Fix

To address this vulnerability, the recommended solution is to upgrade your node-forge version to 1.3.2 or later. This version includes a patch that resolves the Integer Overflow issue, preventing attackers from exploiting the vulnerability. Here’s how to implement the fix:

Type: Upgrade version
Origin: https://github.com/advisories/GHSA-65ch-62r8-g69g
Release Date: 2025-11-26
Fix Resolution: node-forge - 1.3.2

Steps to Upgrade

Update Your Package: Use npm or yarn to update node-forge to the latest version. Run the following command in your project directory:
```
npm install node-forge@latest
```
or, if you're using yarn:
```
yarn upgrade node-forge@latest
```
Verify the Version: After the update, verify that node-forge is upgraded to version 1.3.2 or later by checking your package.json file or running:
```
npm list node-forge
```
or
```
yarn list node-forge
```
Test Your Application: Thoroughly test your application to ensure that the update has not introduced any compatibility issues. Pay close attention to any functionality that uses node-forge for cryptographic operations.
Re-deploy Your Application: Once you have verified that the update is successful and your application is functioning correctly, re-deploy your application to production.

Additional Security Measures

In addition to upgrading node-forge, consider implementing the following security best practices to further protect your application:

Input Validation: Always validate and sanitize input data to prevent injection attacks. This can help mitigate the impact of vulnerabilities like Integer Overflow.
Regular Updates: Keep all your dependencies up to date to ensure that you have the latest security patches.
Security Audits: Conduct regular security audits of your code and infrastructure to identify and address potential vulnerabilities.
Web Application Firewall (WAF): Deploy a WAF to protect your application from common web attacks, including those that exploit vulnerabilities in third-party libraries.

Conclusion

The CVE-2025-66030 vulnerability in node-forge-0.10.0 is a serious issue that should be addressed promptly. By upgrading to version 1.3.2 or later, you can mitigate the risk of exploitation and protect your application from potential attacks. Always stay vigilant and follow security best practices to ensure the ongoing security of your applications. Stay safe out there, guys!
