Vulnerability Details

CVEID:CVE-2020-1971
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference. If the GENERAL_NAME_cmp function contain an EDIPARTYNAME, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/192748 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-8287
**DESCRIPTION:**Node.js is vulnerable to HTTP request smuggling. By sending specially crafted HTTP request headers, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/194100 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)

CVEID:CVE-2020-8265
**DESCRIPTION:**Node.js is vulnerable to a denial of service, caused by a use-after-free in TLSWrap within the TLS implementation. By writing to a TLS enabled socket, an attacker could exploit this vulnerability to corrupt memory and cause a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/194101 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2021-23840
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by an integer overflow in CipherUpdate. By sending an overly long argument, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196848 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2021-22884
**DESCRIPTION:**Node.js is vulnerable to a denial of service, caused by an error when the allowlist includes “localhost6”. By controlling the victim’s DNS server or spoofing its responses, an attacker could exploit this vulnerability to bypass the DNS rebinding protection mechanism using the “localhost6” domain and cause a denial of service.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197191 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H)

CVEID:CVE-2021-22883
**DESCRIPTION:**Node.js is vulnerable to a denial of service, caused by a file descriptor leak. By making multiple attempts to connect with an ‘unknownProtocol’, an attacker could exploit this vulnerability to lead to an excessive memory usage and cause the system to run out of memory.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197190 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2021-23839
**DESCRIPTION:**OpenSSL could provide weaker than expected security, caused by incorrect SSLv2 rollback protection that allows for the inversion of the logic during a padding check. If the server is configured for SSLv2 support at compile time, configured for SSLv2 support at runtime or configured for SSLv2 ciphersuites, it will accept a connection if a version rollback attack has occurred and erroneously reject a connection if a normal SSLv2 connection attempt is made.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196849 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N)

CVEID:CVE-2021-23841
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in the X509_issuer_and_serial_hash() function. By parsing the issuer field, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196847 for the current score.
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

All supported versions (10.x, 12.x, and 14.x) of Node.js are vulnerable.

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

cf ssh <appname> -c “cat app/logs/staging_task.log” | grep “Installing node”
-----> Installing node 10.24.0

Alternatively, through the command-line Cloud Foundry client run the following command:

$ cf ssh <appname> -c “cat app/logs/staging_task.log” | grep “IBM SDK for Node.js”
-----> IBM SDK for Node.js Buildpack v4.6-20210305-2036

If the Buildpack version is not at least v4.6 your application may be vulnerable.

Remediation/Fixes

The fixes for these vulnerabilities are included in Node.js v10.24.0 and subsequent releases.
The fixes for these vulnerabilities are included in Node.js v12.21.0 and subsequent releases.
The fixes for these vulnerabilities are included in Node.js v14.16.0 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”: “10."
},
or
“engines”: {
“node”: "12.”
},
or
“engines”: {
“node”: “14.*”
},

You will then need to restage (or re-push) your application using the IBM SDK for Node.js Buildpack v4.6.
