Vulnerability Details
CVEID: CVE-2022-25857
DESCRIPTION: Java package org.yaml:snakeyam is vulnerable to a denial of service, caused by missing to nested depth limitation for collections. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/234864 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-2022-38751
DESCRIPTION: SnakeYAML is vulnerable to a denial of service, caused by a stack-overflow in parsing YAML files. By persuading a victim to open a specially crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 3.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235311 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2022-38752
DESCRIPTION: SnakeYAML is vulnerable to a denial of service, caused by a stack-overflow in parsing YAML files. By persuading a victim to open a specially crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235310 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-2022-31692
DESCRIPTION: VMware Tanzu Spring Security could allow a remote attacker to bypass security restrictions, caused by a flaw when using forward or include dispatcher types. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass authorization rules.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/239162 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
CVEID: CVE-2021-3754
DESCRIPTION: Keycloak is vulnerable to a denial of service, caused by a flaw with the ability to register using the same username as the email ID of any existing user. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause trouble in getting password recovery email, and results in a denial of service condition.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235009 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2022-2256
DESCRIPTION: Keycloak is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote authenticated attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
CVSS Base score: 3.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235228 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2022-3172
DESCRIPTION: Kubernetes kube-apiserver is vulnerable to server-side request forgery, caused by a flaw with allowing an aggregated API server to redirect client traffic to any URL. By sending a specially-crafted request, an attacker could exploit this vulnerability to conduct SSRF attack to unexpected actions and the client's API server credentials to third parties.
CVSS Base score: 5.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/236344 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:L/A:L)
CVEID: CVE-2022-42003
DESCRIPTION: FasterXML jackson-databind is vulnerable to a denial of service, caused by a lack of a check in the primitive value deserializers when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. By sending a specially-crafted request using deep wrapper array nesting, a local attacker could exploit this vulnerability to exhaust all available resources.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/237662 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2022-42004
DESCRIPTION: FasterXML jackson-databind is vulnerable to a denial of service, caused by a lack of a check in in the BeanDeserializer._deserializeFromArray function. By sending a specially-crafted request using deeply nested arrays, a local attacker could exploit this vulnerability to exhaust all available resources.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/237660 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.
