Security: Fix Certificate Validation and Signature Verification Vulnerabilities

Description

This PR addresses multiple security vulnerabilities in node-forge related to X.509 certificate validation, ASN.1 parsing, and signature verification.

The vulnerabilities can potentially allow malformed or malicious certificates/signatures to bypass validation or be incorrectly interpreted by the library.

Issues addressed

  • BasicConstraints bypass in certificate chain verification

    • Ensures certificate chain validation correctly enforces the BasicConstraints extension as required by RFC 5280.
  • ASN.1 OID Integer Truncation

    • Prevents malformed Object Identifier values from being incorrectly parsed due to integer truncation.
  • ASN.1 Validator Desynchronization

    • Prevents interpretation conflicts caused by crafted ASN.1 structures that can cause the validator and parser to process different portions of the input.
  • Ed25519 signature forgery

    • Adds the required S > L validation check to prevent forged Ed25519 signatures from being accepted.
  • RSA-PKCS signature forgery

    • Strengthens ASN.1 validation to reject signatures containing unexpected or malicious extra fields.

Steps to Reproduce

  1. Create malicious X.509 certificates containing invalid or forged signature data.
  2. Attempt to parse and verify the certificates using node-forge.
  3. Provide crafted ASN.1 inputs designed to trigger OID truncation or validator desynchronization.
  4. Test forged Ed25519 and RSA-PKCS signatures against the affected verification logic.
  5. Observe that malformed certificates/signatures may be incorrectly accepted by vulnerable versions.

Expected Behavior

node-forge should:

  • Correctly enforce X.509 BasicConstraints according to RFC 5280.
  • Reject malformed or overflowing ASN.1 OID values.
  • Keep ASN.1 validators synchronized with the actual parsed structure.
  • Reject Ed25519 signatures where S > L.
  • Reject RSA-PKCS signatures containing unexpected ASN.1 fields.
  • Never accept malformed certificates or forged signatures as valid.

Changes

The implementation:

  • Strengthens X.509 certificate-chain validation.
  • Adds stricter ASN.1/OID parsing validation.
  • Prevents ASN.1 validator/parser desynchronization.
  • Adds strict Ed25519 scalar validation.
  • Tightens RSA-PKCS signature ASN.1 validation.
  • Adds regression tests covering the affected attack cases.

Testing

The affected certificate and signature verification paths were tested with both valid inputs and maliciously crafted inputs.

Regression tests verify that:

  • Valid certificates continue to verify successfully.
  • Invalid BasicConstraints configurations are rejected.
  • Malformed ASN.1 OIDs are rejected.
  • ASN.1 validator desynchronization payloads are rejected.
  • Ed25519 signatures with invalid S values are rejected.
  • RSA-PKCS signatures containing unexpected ASN.1 data are rejected.

Security Impact

These fixes prevent malformed certificates, crafted ASN.1 structures, and forged signatures from bypassing security validation in applications relying on node-forge.

This PR is intended as a security hardening and vulnerability remediation change while maintaining compatibility with valid certificates and signatures.

Warning

There were issues while running some tools. Please review the errors and either fix the tool's configuration or disable the tool if it's a critical failure.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

ESLint install failed: dependency version conflict. Check your lock file or package.json.

Restore the compatible react-scripts version.

package.json declares react-scripts as ^0.0.0, and package-lock.json resolves it to the 0.0.0 tarball. The repository’s eject script calls react-scripts eject, so react-scripts@0.0.0 leaves that script broken. Restore the previous compatible version or range and regenerate the lockfile.
