An attacker could exploit this vulnerability using a 0-byte record padding-oracle attack to decrypt traffic. CVSS Base Score: 5.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 157514 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N) CVEID: CVE-2019-5737 DESCRIPTION: Node.js is vulnerable to a denial of service. By establishing an HTTP or HTTPS connection in keep-alive mode and sending headers very slowly to force the connection and associated resources to stay alive for a long period of time, a remote attacker could exploit this vulnerability to consume all available resources.
