CVE-2023-30589
Description
A vulnerability has been identified in the Node.js, where llhttp parser in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS).
Statement
The vulnerability is in the llhttp parsing not using the CRLF sequence which violates the HTTP/1.1 specification, which mandates CRLF as the delimiter. While this might result in request smuggling, the added complexity of creating a valid malformed delimited request and having it reach the intended target and then processed,which is why this has been rated 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).
