Summary
There are multiple vulnerabilities in Node.js used by IBM Cloud App Management
V2018. IBM Cloud App Management has addressed the applicable CVEs in a later
version.
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-2018-12123
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/
153457 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)
