Vulnerability Details

CVEID: CVE-2019-1559 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by the failure to immediately close the TCP connection after the hosts encounter a zero-length record with valid padding. 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&gt; 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.
CVSS Base Score: 5.9
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/158093&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2019-5739 DESCRIPTION: Node.js is vulnerable to a denial of service. By establishing an HTTP or HTTPS connection in keep-alive mode forcing the connection to remain open and inactive for up to 2 minutes, a remote attacker could exploit this vulnerability to consume all available resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/158096&gt; 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)

Affected Products and Versions

These vulnerabilities affect IBM SDK for Node.js v6.15.0 and earlier releases.
These vulnerabilities affect IBM SDK for Node.js v8.14.0 and earlier releases.

These vulnerabilities affect IBM SDK for Node.js v10.14.0.0 and earlier releases.

Through the command-line Cloud Foundry client run the following command:

cf ssh <appname> -c “cat staging_info.yml”

Look for the following lines:
{“detected_buildpack”:“SDK for Node.js™ (node.js-xxx, buildpack-v3.xxx)”,“start_command”:“./vendor/initial_startup.rb”}

If the Node.js engine version is not at least v6.17.0, v8.15.1 or v10.15.2 your application may be vulnerable.

Remediation/Fixes

The fixes for these vulnerabilities are included in IBM SDK for Node.js v6.17.0 and subsequent releases.
The fixes for these vulnerabilities are included in IBM SDK for Node.js v8.15.1 and subsequent releases.

The fixes for these vulnerabilities are included in IBM SDK for Node.js v10.15.2 and subsequent releases.

To upgrade to the latest version of the Node.js runtime, please specify the latest Node.js runtime in your package.json file for your application:

“engines”: {
“node”: “>=6.17.0”
},
_or _
“engines”: {
“node”: “>=8.15.1”
},

_or _
“engines”: {
“node”: “>=10.15.2”
},

You will then need to restage (or re-push) your application using the IBM SDK for Node.js Buildpack v3.26.

Workarounds and Mitigations

None.
