CVE-2023-43497 Open this link in a new tabHow to fix?
Upgrade org.jenkins-ci.main:jenkins-core to version 2.414.2, 2.424 or higher.
Overview
org.jenkins-ci.main:jenkins-core is an open source automation server.
Affected versions of this package are vulnerable to Incorrect Default Permissions via the MultipartFormDataParser API and the Stapler web framework. An attacker can read and write temporary files before they are used by exploiting the default permissions for newly created files in the system temporary directory.
Note:
This is only exploitable if the operating system uses a shared temporary directory for all users (typically Linux).
Workaround
This vulnerability can be mitigated by changing your default temporary-file directory using the Java system property java.io.tmpdir.
