Security Bulletin
Summary
There are multiple vulnerabilities in components of IBM i Modernization Engine for Lifecycle Integration as described in the Vulnerability Details section. Google Guava and Apache James MIME4J could allow a local authenticated attacker to obtain sensitive information. Pivota Spring Framework could allow a remote attacker to execute arbitrary code on the system. Keycloak could allow a remote attacker to obtain sensitive information and could allow a remote attacker to conduct spoofing attacks. VMware Tanzu Spring Boot is vulnerable to a denial of service. RESTEasy could allow a local authenticated attacker to gain elevated privileges on the system. These components are used in IBM i Modernization Engine for Lifecycle Integration for infrastructure support in the platform. IBM has addressed the vulnerabilities in IBM i Modernization Engine for Lifecycle Integration with updates to affected components.
Vulnerability Details
CVEID: CVE-2023-2585
DESCRIPTION: Keycloak could allow a remote attacker to conduct spoofing attacks, caused by a flaw in the Device Authorisation Grant. An attacker could exploit this vulnerability to spoof parts of the device flow and use a device_code to retrieve an access token for other OAuth clients.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/261772 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N)
CVEID: CVE-2023-0482
DESCRIPTION: RESTEasy could allow a local authenticated attacker to gain elevated privileges on the system, caused by the creation of insecure temp files in the File.createTempFile() used in the DataSourceProvider, FileProvider and Mime4JWorkaround classes. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246304 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2023-20883
DESCRIPTION: VMware Tanzu Spring Boot is vulnerable to a denial of service, caused by a flaw when Spring MVC is used together with a reverse proxy cache. By sending a specially crafted request, 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/255809 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-2023-1664
DESCRIPTION: Keycloak could allow a remote attacker to obtain sensitive information, caused by a flaw when using X509 Client Certificate Authenticatior with the option "Revalidate Client Certificate". By using a specially crafted certificate, 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: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/256644 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2016-1000027
DESCRIPTION: Pivota Spring Framework could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe deserialization flaw in the library. By sending specially-crafted input, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/174367 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2022-45787
DESCRIPTION: Apache James MIME4J could allow a local authenticated attacker to obtain sensitive information, caused by improper laxist permissions on the temporary files. By sending a specially-crafted request, 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: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/244033 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2023-2976
DESCRIPTION: Google Guava could allow a local authenticated attacker to obtain sensitive information, caused by a flaw with using Java's default temporary directory for file creation in FileBackedOutputStream. By sending a specially crafted request, an attacker could exploit this vulnerability to access the files in the default Java temporary directory, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258199 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.
