SECURITY BULLETIN: MULTIPLE VULNERABILITIES IN VMWARE VCENTER AFFECT IBM CLOUD
PAK SYSTEM
SECURITY BULLETIN
SUMMARY
Multiple vulnerabilities in VMware vCenter plugins affect IBM Cloud Pak System.
IBM Cloud Pak System in response to the vulnerabilities in VMware vCenter,
provides the new release of IBM Cloud Pak System V2.3.3.4, with a new vCenter
Image.
VULNERABILITY DETAILS
CVEID: CVE-2021-21985
DESCRIPTION: VMware vCenter Server and Cloud Foundation could allow a remote
attacker to execute arbitrary commands on the system, caused by improper
validation of user-supplied input by the Virtual SAN Health Check plug-in which
is enabled by default in vCenter Server. By sending a specially-crafted request
using port 443, an attacker could exploit this vulnerability to execute
arbitrary commands with unrestricted privileges on the underlying operating
system that hosts vCenter Server.
CVSS Base score: 9.8
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/202404 for the current
score.

CVEID: CVE-2021-21986
DESCRIPTION: VMware vCenter Server and Cloud Foundation could allow a remote
attacker to bypass security restrictions, caused by a flaw in a vSphere
authentication mechanism for the Virtual SAN Health Check, Site Recovery,
vSphere Lifecycle Manager, and VMware Cloud Director Availability plug-ins. By
sending a specially-crafted request using port 443, an attacker could exploit
this vulnerability to bypass authentication and perform actions allowed by the
impacted plug-ins without authentication.
CVSS Base score: 6.5
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/202403 for the current
score.

CVEID: CVE-2021-21991
DESCRIPTION: VMware vCenter Server and Cloud Foundation could allow a local
authenticated attacker to gain elevated privileges on the system, caused by
improper handling of session tokens. An attacker could exploit this
vulnerability to escalate privileges to Administrator on the vSphere Client.
CVSS Base score: 8.8
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/209752 for the current

CVEID: CVE-2021-21992
DESCRIPTION: VMware vCenter Server and Cloud Foundation are vulnerable to a
denial of service, caused by improper XML entity parsing. A remote authenticated
attacker could exploit this vulnerability to cause a denial of service on the
vCenter Server host.
CVSS Base score: 6.5
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/209751 for the current
score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2021-21993
DESCRIPTION: VMware vCenter Server and Cloud Foundation are vulnerable to
server-side request forgery, caused by improper validation of URLs in vCenter
Server Content Library. By sending a specially-crafted POST request, a remote
authenticated attacker could exploit this to obtain sensitive information.
CVSS Base score: 4.3
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/209750 for the current
score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2021-22006
DESCRIPTION: VMware vCenter Server and Cloud Foundation could allow a remote
attacker to bypass security restrictions, caused by improper handling of the URI
by endpoints. An attacker could exploit this vulnerability to access restricted
endpoints.
CVSS Base score: 8.3
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/209748 for the current
score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L)
CVEID: CVE-2021-22008
DESCRIPTION: VMware vCenter Server could allow a remote attacker to obtain
sensitive information. By sending a specially crafted jsonrpc message, a remote
attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 5.3
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/209746 for the current
score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2021-22009
DESCRIPTION: VMware vCenter Server and Cloud Foundation are vulnerable to a
denial of service, caused by an error in VAPI (vCenter API) service. A remote
attacker could exploit this vulnerability to consume excessive memory resources.
CVSS Base score: 5.3
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/209745 for the current
score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2021-22010
DESCRIPTION: VMware vCenter Server and Cloud Foundation are vulnerable to a
denial of service, caused by an error in VPXD (Virtual Provisioning X Daemon)
service. A remote attacker could exploit this vulnerability to consume excessive
memory resources.
CVSS Base score: 5.3
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/209744 for the current
score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2021-22016
DESCRIPTION: VMware vCenter Server is vulnerable to cross-site scripting,
caused by improper validation of user-supplied input. A remote attacker could
exploit this vulnerability using a specially-crafted URL to execute script in a
victim's Web browser within the security context of the hosting Web site, once
the URL is clicked. An attacker could use this vulnerability to steal the
victim's cookie-based authentication credentials.

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.
