Vulnerability Details
CVEID: CVE-2018-12122
DESCRIPTION: Node.js is vulnerable to a denial of service, caused by improper validation of HTTP headers. By sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/153456 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2018-12121
DESCRIPTION: Node.js is vulnerable to a denial of service, caused by improper validation of HTTP headers. By sending specially-crafted HTTP requests with maximum sized headers, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/153455 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2018-12116
DESCRIPTION: Node.js is vulnerable to HTTP request splitting attacks, caused by improper input validation by the path option of an HTTP request. A remote attacker could exploit this vulnerability to inject arbitrary HTTP request and cause the browser to send 2 HTTP requests, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting.
CVSS Base Score: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/153452 for the current score
