CVE-2023-30590
Description
A vulnerability has been identified in the Node.js, where a generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or outdated) keys, that is, it only generates a private key if none has been set yet.
Statement
The generateKeys() API function returned from crypto.createDiffieHellman() in Node.js does not behave as documented as the documentation states that the function “generates private and public Diffie-Hellman key values.” However, the actual implementation only generates a private key if one has not yet been set, and does not recompute or regenerate the public key if the private key was previously defined using setPrivateKey(), which is why this could only in theory, result in weak or predictable shared secrets. The issue at hand is a developer facing hazard caused by a mismatch in the documentation and application of the function, and is not in itself a security vulnerability, which is why Redhat has assessed this as moderate.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
