Vulnerability Details
CVEID: CVE-2023-20862
DESCRIPTION: VMware Tanzu Spring Security could allow a remote attacker to bypass security restrictions, caused by the logout support feature does not properly clean the security context if using serialized versions. By sending a specially-crafted request, an attacker could exploit this vulnerability to remain authenticated after logout is performed.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/253351 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-2022-43928
DESCRIPTION: The IBM Toolbox for Java (Db2 Mirror for i 7.4 and 7.5) could allow a user to obtain sensitive information, caused by utilizing a Java string for processing. Since Java strings are immutable, their contents exist in memory until garbage collected. This means sensitive data could be visible in memory over an indefinite amount of time. IBM has addressed this issue by reducing the amount of time the sensitive data is visible in memory. IBM X-Force ID: 241675.
CVSS Base score: 4.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/241675 for the current score.

CVEID: CVE-2022-45688
DESCRIPTION: Hutool is vulnerable to a denial of service, caused by stack-based buffer overflow. By persuading a specially crafted request, a remote 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/242881 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-2023-24998
DESCRIPTION: Apache Commons FileUpload and Tomcat are vulnerable to a denial of service, caused by not limit the number of request parts to be processed in the file upload function. By sending a specially-crafted request with series of uploads, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/247895 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-2022-41854
DESCRIPTION: snakeYAML is vulnerable to a denial of service, caused by improper input validation. By persuading a victim to open a specially-crafted YAML content, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240890 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-20860
DESCRIPTION: VMware Tanzu Spring Framework could allow a remote attacker to bypass security restrictions, caused by the use of an un-prefixed double wildcard pattern with the mvcRequestMatcher in Spring Security configuration. An attacker could exploit this vulnerability to create a mismatch in pattern matching between Spring Security and Spring MVC.
CVSS Base score: 9.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/250679 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N)
CVEID: CVE-2023-20859
DESCRIPTION: VMware Tanzu Spring Vault could allow a local authenticated attacker to obtain sensitive information, caused by the insertion of sensitive information into log sourced from failed revocation of tokens. By gaining access to the log files, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 4.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/250863 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2023-20861
DESCRIPTION: VMware Tanzu Spring Framework is vulnerable to a denial of service. By sending a specially crafted SpEL expression, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/250701 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.
