Security Bulletin

Summary

Node.js, as well as many other implementations of HTTP/2, have been found
vulnerable to Denial of Service attacks.

Vulnerability Details

CVEID: CVE-2019-9517
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by
an Internal Data Buffering attack. By opening the HTTP/2 window so the peer can
send without constraint and sending a stream of requests for a large response
object, a remote attacker could consume excessive CPU resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
165183 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-2019-9518
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by
a Empty Frame Flooding attack. By sending a stream of frames with an empty
payload and without the end-of-stream flag, a remote attacker could consume
excessive CPU resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

CVEID: CVE-2019-9515
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by
a Settings Flood attack. By sending a stream of SETTINGS frames to the peer, a
remote attacker could consume excessive CPU resources.

CVEID: CVE-2019-9516
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by
a 0-Length Headers Leak attack. By sending a stream of headers with a 0-length
header name and 0-length header value, a remote attacker could consume
excessive memory resources.
CVSS Base Score: 7.5

CVEID: CVE-2019-9513
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by
a Resource Loop attack. By creating multiple request streams and continually
shuffling the priority of the streams, a remote attacker could consume
excessive CPU resources.

CVEID: CVE-2019-9514
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by
a Reset Flood attack. By opening a number of streams and sending an invalid
request over each stream, a remote attacker could consume excessive CPU
resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2019-9511
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by
a Data Dribble attack. By sending a HTTP/2 request by the HTTP/2 protocol stack
(HTTP.sys) for an overly large amount of data from a specified resource over
multiple streams, a remote attacker could consume excessive CPU resources.
CVSS Base Score: 7.5

CVEID: CVE-2019-9512
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by
a Ping Flood attack. By sending continual pings to an HTTP/2 peer, a remote
attacker could consume excessive CPU resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
164903 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 affectNode.js v8.15.1and earlier releases.

These vulnerabilities affect Node.js v10.15.2and earlier releases.

These vulnerabilities affect Node.js v12.7.1and earlier releases.

Through the command-line Cloud Foundry clientrunthe following command:

cf ssh <appname> -c "cat staging_info.yml"

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

If the Node.js engine version is not at least v8.16.1 or v10.16.3 or
v12.8.1your application may be vulnerable.

Remediation/Fixes

The fixes for these vulnerabilities are included in Node.js v8.16.1and
subsequent releases.
The fixes for these vulnerabilities are included in Node.js v10.16.3and
subsequent releases.

The fixes for these vulnerabilities are included in Node.js v12.8.1 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": ">=8.16.1 <10.0.0"
},
or
"engines": {
"node": ">=10.16.3 <12.0.0"
},

or
"engines": {
"node": ">=12.8.1"
},

You will then need to restage (or re-push) your application using the IBM SDK for Node.js Buildpack v4.0.

Workarounds and Mitigations

None.
