CVE-2023-25653 Improper calculations in ECC implementation can trigger a Denial-of-Service (DoS)

What is CVE-2023-25653?

CVE-2023-25653 is a high-severity denial of service vulnerability in cisco node-jose, published on 16 Feb 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

node-jose is a JavaScript implementation of the JSON Object Signing and Encryption (JOSE) for web browsers and node.js-based servers. Prior to version 2.2.0, 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. The issue has been patched in version 2.2.0. Since this issue is only present in the "fallback" crypto implementation, it can be avoided by ensuring that either WebCrypto or the Node `crypto` module is available in the JS environment where `node-jose` is being run.

Weakness: CWE-835
