Описание
A flaw in Node.js 20's HTTP parser allows improper termination of HTTP/1 headers using \r\n\rX instead of the required \r\n\r\n.
This inconsistency enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests.
The issue was resolved by upgrading llhttp to version 9, which enforces correct header termination.
Impact:
- This vulnerability affects only Node.js 20.x users prior to the
llhttpv9 upgrade.
A flaw was found in the HTTP parser of Node.js. This vulnerability allows attackers to perform request smuggling and bypass proxy-based access controls via improperly terminated HTTP/1 headers using \r\n\rX instead of the standard \r\n\r\n.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
