CVE-2023-25653Improper calculations in ECC implementation can trigger a Denial-of-Service (DoS)
High 7.5
In plain English
A high-severity infinite loop in node-jose from cisco. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.6% (higher than 46% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
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.
