Vulnerability Details
CVEID: CVE-2019-11250
DESCRIPTION: Kubernetes could allow a remote attacker to obtain sensitive information, caused by storing credentials in the log by the client-go library. By sending a specially-crafted command, a remote attacker could exploit this vulnerability to obtain sensitive information and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/166710 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2019-11247
DESCRIPTION: Kubernetes could allow a remote authenticated attacker to gain unauthorized access to the system, caused by an error in the API server. By sending a specially crafted request using the wrong scope, an attacker could exploit this vulnerability to create, view, update or delete the cluster-scoped resource.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/164767 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N)
CVEID: CVE-2020-10752
DESCRIPTION: OpenShift API Server could allow a remote attacker to obtain sensitive information, caused by the leaking of OAuthTokens to log files when API Server panic occurred. By gaining access to the log files, an attacker could exploit this vulnerability to obtain OAuthTokens information, and use this information to launch further attacks against the affected system.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/184792 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N)
CVEID: CVE-2020-8565
DESCRIPTION: Kubernetes could allow a local authenticated attacker to obtain sensitive information, caused by a flaw when kube-apiserver is using logLevel >= 9. By gaining access to the log files, an attacker could exploit this vulnerability to obtain the Kubernetes authorization tokens information, and use this information to launch further attacks against the affected system.
CVSS Base score: 4.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/189925 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2020-27813
DESCRIPTION: Gorilla WebSocket is vulnerable to a denial of service, caused by an integer overflow with the length of websocket frames received. By sending a specially-crafted websocket connection request, a remote attacker could exploit this vulnerability to cause a denial of service condition on the HTTP Server.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/192563 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-2021-3121
DESCRIPTION: An unspecified error with the lack of certain index validation, aka the skippy peanut butter issue in GoGo Protobuf has an unknown impact and attack vector.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/194539 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-2021-25735
DESCRIPTION: Kubernetes kube-apiserver could allow a remote authenticated attacker to bypass security restrictions, caused by a flaw when performing note updates. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass a Validating Admission Webhook.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/199931 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H)
CVEID: CVE-2020-26160
DESCRIPTION: jwt-go could allow a remote attacker to bypass security restrictions, caused by a type assertion failure when m["aud"] happens to be []string{}. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass access restrictions.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/189408 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.
