Summary

Multiple vulnerabilities in Node.js that is used by IBM InfoSphere Information Server were addressed.

Vulnerability Details

CVEID:CVE-2021-22959
**DESCRIPTION:**Node.js is vulnerable to HTTP request smuggling, caused by an error related to a space in headers. A remote attacker could send a specially-crafted request with a space (SP) right after the header name before the colon to lead to HTTP Request Smuggling (HRS). An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/211168 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

CVEID:CVE-2021-44533
**DESCRIPTION:**Node.js could allow a remote attacker to bypass security restrictions, caused by the incorrect handling of multi-value Relative Distinguished Names. By crafting certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, an attacker could exploit this vulnerability to bypass the certificate subject verification.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216932 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2021-44532
**DESCRIPTION:**Node.js could allow a remote attacker to bypass security restrictions, caused by a string injection vulnerability when name constraints were used within a certificate chain. An attacker could exploit this vulnerability to bypass the name constraints.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216931 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2021-22960
**DESCRIPTION:**Node.js is vulnerable to HTTP request smuggling, caused by an error when parsing the body of chunked requests. A remote attacker could send a specially-crafted request to lead to HTTP Request Smuggling (HRS). An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/211171 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

CVEID:CVE-2021-44531
**DESCRIPTION:**Node.js could allow a remote attacker to bypass security restrictions, caused by the improper handling of URI Subject Alternative Name (SAN) types. An attacker could exploit this vulnerability to bypass name-constrained intermediates.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216930 for the current score.
