Security Bulletin: IBM Event Streams is potentially affected by multiple node vulnerabilities

Description

## Summary The IBM Event Streams UI is potentially affected by multiple node vulnerabilities ## Vulnerability Details ** CVEID: **[CVE-2021-3189](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3189>) ** DESCRIPTION: **Nodejs slashify module could allow a remote attacker to conduct phishing attacks, caused by an open redirect vulnerability. An attacker could exploit this vulnerability using a specially-crafted URL to redirect a victim to arbitrary Web sites. CVSS Base score: 7.4 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/197154](<https://exchange.xforce.ibmcloud.com/vulnerabilities/197154>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N) ** CVEID: **[CVE-2021-23840](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=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](<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](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=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](<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](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=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](<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-2020-1971](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=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](<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](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=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](<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](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=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](<https://exchange.xforce.ibmcloud.com/vulnerabilities/194101>) for the current score.

Customers can evaluate the impact of this vulnerability in their environments by accessing the links in the Reference section of this Security Bulletin. ## 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. ## Document Location Worldwide [{"Business Unit":{"code":"BU059","label":"IBM Software w\/o TPS"},"Product":{"code":"SSFHBB","label":"IBM Event Streams"},"Component":"","Platform":[{"code":"PF016","label":"Linux"},{"code":"PF051","label":"Linux on IBM Z Systems"}],"Version":"2019.4.x, 10.x","Edition":"","Line of Business":{"code":"LOB45","label":"Automation"}}]
