## Summary

IBM Engineering Requirements Quality Assistant On-Premises affected by multiple vulnerabilites (CVE-2021-22939, CVE-2021-22931, CVE-2020-7598) which allowed a remote attacker to exploit this vulnerability to add or modify properties of Object.prototype, connect to servers using an expired certificate and injection vulnerabilities in applications using the library by Domain Hijacking.

## 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-2021-22931]()
** DESCRIPTION: **Node.js could provide weaker than expected security, caused by missing input validation on hostnames returned by DNS servers. An attacker could exploit this vulnerability to cause output of wrong hostnames leading to Domain Hijacking and and injection vulnerabilities in applications using the library.
CVSS Base score: 5
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/207230]() for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L)

** CVEID: **[CVE-2020-7598]()
** DESCRIPTION: **minimist could provide weaker than expected security, caused by a prototype pollution flaw. By sending a specially crafted request, a remote attacker could exploit this vulnerability to add or modify properties of Object.prototype.
CVSS Base score: 5.3
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/177780]() 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)

## 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.
