    Infinite loop

    node-jose is a JavaScript implementation of the JSON Object Signing and Encryption (JOSE) for current web browsers and node.js-based servers.

    Affected versions of this package are vulnerable to Infinite loop such that when using the non-default "fallback" crypto back-end, ECC operations in node-jose can trigger a Denial-of-Service (DoS) condition, due to a possible infinite loop in an internal calculation. For some ECC operations, this condition is triggered randomly; for others, it can be triggered by malicious input.

    Impact: This issue is only present in situations where the "fallback" cryptographic implementation is being used, i.e., situations where neither WebCrypto nor the Node crypto module is available.

    The following elliptic curve algorithms are impacted by this issue (all in lib/deps/ecc/index.js):

    1. Elliptic curve key generation (exports.generateKeyPair)

    2. Converting an elliptic curve private key to a public key (ECPrivateKey.prototype.toPublicKey)

    3. ECDSA signing (ECPrivateKey.prototype.sign)

    4. ECDSA verification (ECPublicKey.prototype.verify)

    5. ECDH key agreement (ECPrivateKey.prototype.computeSecret)

    How to fix Infinite loop?

    Upgrade node-jose to version 2.2.0 or higher.

    Insecure Token Validation

    node-jose is a JavaScript implementation of the JSON Object Signing and Encryption (JOSE) for current web browsers and node.js-based servers.

    A vulnerability in the Cisco node-jose open source library before 0.11.0 could allow an unauthenticated, remote attacker to re-sign tokens using a key that is embedded within the token. The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header.
