CVE-2023-43496

8.8 highEPSS 1.0%

High (8.8) in jenkins jenkins. EPSS 1.0% chance of exploitation in the next 30 days. Fixed in org.jenkins-ci.main:jenkins-core 2.414.2, 2.424.

Jenkins 2.423 and earlier, LTS 2.414.1 and earlier creates a temporary file in the system temporary directory with the default permissions for newly created files when installing a plugin from a URL, potentially allowing attackers with access to the system temporary directory to replace the file before it is installed in Jenkins, potentially resulting in arbitrary code execution.
