Security Bulletin: Multiple vulnerabilities in Node.js and OpenSSL affect IBM
Watson Assistant on IBM Cloud Private

Document information

More support for: IBM Cloud Private

Component: IBM Watson Assistant

Software version: All Versions

Operating system(s): Linux

Reference #: 0871922

Modified date: 21 February 2019

Summary

Multiple vulnerabilities in Node.js(TM) and OpenSSL (as used by Node.js) that
affect IBM(R) Watson(TM) Assistant on IBM Cloud Private were disclosed by the
Node.js foundation and OpenSSL project.

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
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)
