node-forge@0.2.11 vulnerabilities

node-forge is a JavaScript implementations of network transports, cryptography, ciphers, PKI, message digests, and various utilities.

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to RSA's PKCS#1 v1.5 signature verification code which does not properly check DigestInfo for a proper ASN.1 structure. This can lead to successful verification with signatures that contain invalid structures but a valid digest.

Upgrade node-forge to version 1.3.0 or higher.

node-forge is a JavaScript implementations of network transports, cryptography, ciphers, PKI, message digests, and various utilities.

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to RSAs PKCS#1` v1.5 signature verification code which is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used.

Upgrade node-forge to version 1.3.0 or higher.

node-forge is a JavaScript implementations of network transports, cryptography, ciphers, PKI, message digests, and various utilities.

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to RSA's PKCS#1 v1.5 signature verification code which does not check for tailing garbage bytes after decoding a DigestInfo ASN.1 structure. This can allow padding bytes to be removed and garbage data added to forge a signature when a low public exponent is being used.

Upgrade node-forge to version 1.3.0 or higher.

node-forge is a JavaScript implementations of network transports, cryptography, ciphers, PKI, message digests, and various utilities.

Affected versions of this package are vulnerable to Prototype Pollution via the forge.debug API if called with untrusted input.

Upgrade node-forge to version 1.0.0 or higher.

node-forge is a JavaScript implementations of network transports, cryptography, ciphers, PKI, message digests, and various utilities.

Affected versions of this package are vulnerable to Open Redirect via parseUrl function when it mishandles certain uses of backslash such as https:/\/\/\ and interprets the URI as a relative path.

PoC:

// poc.js
var forge = require("node-forge");
var url = forge.util.parseUrl("https:/\/\/\www.github.com/foo/bar");
console.log(url);

// Output of node poc.js:

{
  full: 'https://',
  scheme: 'https',
  host: '',
  port: 443,
  path: '/www.github.com/foo/bar',                        <<<---- path  should be "/foo/bar"
  fullHost: ''
}

Upgrade node-forge to version 1.0.0 or higher.

node-forge is a JavaScript implementations of network transports, cryptography, ciphers, PKI, message digests, and various utilities.

Affected versions of this package are vulnerable to Prototype Pollution via the util.setPath function.

Note: version 0.10.0 is a breaking change removing the vulnerable functions.

POC:

const nodeforge = require('node-forge');
var obj = {};
nodeforge.util.setPath(obj, ['__proto__', 'polluted'], true);
console.log(polluted);

Upgrade node-forge to version 0.10.0 or higher.

node-forge is a native implementation of TLS (and various other cryptographic tools) in JavaScript.

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks. This can cause an impact of about 10 seconds matching time for data 3K characters long.

Update node-forge to version 0.7.4 or higher.

node-forge is a JavaScript implementation of network transports, cryptography, ciphers, PKI, message digests, and various utilities. Affected versions of the package are vulnerable to a Timing Attack due to unsafe HMAC comparison. The HMAC algorithm produces a keyed message by pairing a hash function with a cryptographic key. Both the key and a message serve as input to this algorithm, while it outputs a fixed-length digest output which can be sent with the message. Anyone who knows the key can repeat the algorithm and compare their calculated HMAC with one they have received, to verify a message originated from someone with knowledge of the key and has not been tampered with.

The problem begins when trying to compare two HMACs. This is the part of code that handles the comparison:

if(byteArrayA.length != byteArrayB.length) { return false; }
for(int i = 0; i < byteArrayA.length; i++) {
  if(byteArrayA[i] != byteArrayB[i]) { return false; }
}
return true;

The issue is that the more bytes match in the two arrays, the more comparisons are formed and the longer it'll take to return a result. This may allow attackers to brute force their way into the servers.

Upgrade node-forge to version 0.6.33 or higher.
