CVE-2023-43496 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 Improper Control of Generation of Code ('Code Injection') when the temporary file creation process is initiated during plugin installation from a URL. An attacker can replace the file before it is installed, potentially leading to arbitrary code execution.
Note: This is only exploitable if the attacker has access to the system temporary directory.
Workaround
Users unable to upgrade to the fixed version can change the default temporary-file directory using the Java system property java.io.tmpdir .
