Summary

Multiple Node.js vulnerabilities were disclosed by the Node.js project. Node.js
is used by the Cordova tools in IBM Rational Application Developer for
WebSphere Software. IBM Rational Application Developer for WebSphere Software
has addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2018-0734
Description: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a timing side channel attack in the DSA signature
algorithm. An attacker could exploit this vulnerability using variations in the
signing algorithm to recover the private key.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152085 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-0735
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a timing side channel attack in the ECDSA signature
algorithm. An attacker could exploit this vulnerability using variations in the
signing algorithm to recover the private key.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
133784 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
 
CVE-ID: CVE-2018-5407
Description: Multiple SMT/Hyper-Threading architectures and processors could
allow a local attacker to obtain sensitive information, caused by execution
engine sharing on Simultaneous Multithreading (SMT) architecture. By using the
PortSmash new side-channel attack, an attacker could run a malicious process
next to legitimate processes using the architectur's parallel thread running
capabilities to leak encrypted data from the CPU's internal processes. Note:
This vulnerability is known as PortSmash.
CVSS Base Score: 5.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152484 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
 
CVE-ID: 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 more information.
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)
 
CVE-ID: 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 more information.
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)
 
CVE-ID: CVE-2018-12120
Description: Node.js could allow a remote attacker to execute arbitrary
JavaScript on the system, caused by a flaw when debugger mode is enabled with
`node --debug` or `node debug`. By sending specially-crafted request to port
5858, an attacker could exploit this vulnerability to execute arbitrary
JavaScript on the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
153454 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
 
CVE-ID: 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 more information.
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)
 
CVE-ID: 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 more information.
CVSS Environmental Score*: Undefined
