## Vulnerability Details

** CVEID: **[CVE-2021-22939]()
** DESCRIPTION: **Node.js could allow a remote attacker to bypass security restrictions. If the https API was used incorrectly and “undefined” was in passed for the “rejectUnauthorized” parameter, an attacker could exploit this vulnerability to connect to servers using an expired certificate.
CVSS Base score: 3.7
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/207233]() for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/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.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/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-2021-37701]()
** DESCRIPTION: **Node.js tar module could allow a local attacker to execute arbitrary code on the system, caused by an arbitrary file creation/overwrite vulnerability. By creating a directory, and then replacing that directory with a symlink, an attacker could use an untrusted tar file to symlink into an arbitrary location and extract arbitrary files into that location to create or overwrite arbitrary files and execute arbitrary code on the system.
CVSS Base score: 8.2
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/208442]() for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N)

** CVEID: **[CVE-2021-37712]()
** DESCRIPTION: **Node.js tar module could allow a local attacker to execute arbitrary code on the system, caused by an arbitrary file creation/overwrite vulnerability. By creating a directory, and then replacing that directory with a symlink that had a different apparent name that resolved to the same entry in the filesystem, an attacker could use an untrusted tar file to symlink into an arbitrary location and extract arbitrary files into that location to create or overwrite arbitrary files and execute arbitrary code on the system.
CVSS Base score: 8.2
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/208450]() for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N)

** 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-2021-44532]()
** 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.

** CVEID: **[CVE-2021-37713]()
** DESCRIPTION: **Node.js tar module could allow a local attacker to execute arbitrary code on the system, caused by insufficient logic on Windows systems when extracting tar files that contained a path that was not an absolute path, but specified a drive letter different from the extraction target. An attacker could exploit this vulnerability to create or overwrite arbitrary files and execute arbitrary code on the system.
CVSS Base score: 8.2
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/208451]() for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N)

** CVEID: **[CVE-2021-39135]()
** DESCRIPTION: **Node.js @npmcli/arborist module could allow a local attacker to launch a symlink attack. By replacing the node_modules folder of the root project or any of its dependencies with a symbolic link, an attacker could exploit this vulnerability to write package dependencies to any arbitrary location on the file system.
CVSS Base score: 8.2
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/208464]() for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N)

** CVEID: **[CVE-2021-39134]()
** DESCRIPTION: **Node.js @npmcli/arborist module could allow a local attacker to launch a symlink attack, caused by the failure of multiple dependencies to coexist within the same level in the node_modules hierarchy. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to various files on the system, which could allow the attacker to create and overwrite arbitrary files on the system with elevated privileges.
CVSS Base score: 8.2
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/208462]() for the current score.

** 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.

## Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an “industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response.” IBM PROVIDES THE CVSS SCORES “”AS IS”” WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. “Affected Products and Versions” referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
