Vulnerability from cvelistv5 – Published: 2023-03-08 17:14 – Updated: 2025-02-28 18:36

Summary

Jenkins 2.393 and earlier, LTS 2.375.3 and earlier creates a temporary file in the default temporary directory with the default permissions for newly created files when uploading a plugin for installation, potentially allowing attackers with access to the Jenkins controller file system to read and write the file before it is used, potentially resulting in arbitrary code execution.

GHSA-HF9H-VV4M-2F33

Vulnerability from github – Published: 2023-03-10 21:30 – Updated: 2024-01-05 13:23

Summary

Incorrect Authorization in Jenkins Core

Details

Jenkins creates a temporary file when a plugin is uploaded from an administrator’s computer.

Jenkins 2.393 and earlier, LTS 2.375.3 and earlier, and prior to LTS 2.387.1 creates this temporary file in the system temporary directory with the default permissions for newly created files.

If these permissions are overly permissive, they may allow attackers with access to the Jenkins controller file system to read and write the file before it is installed in Jenkins, potentially resulting in arbitrary code execution.

This vulnerability only affects operating systems using a shared temporary directory for all users (typically Linux). Additionally, the default permissions for newly created files generally only allows attackers to read the temporary file. Jenkins 2.394, LTS 2.375.4, and LTS 2.387.1 creates the temporary file with more restrictive permissions.

As a workaround, you can set a different path as your default temporary directory using the Java system property java.io.tmpdir, if you’re concerned about this issue but unable to immediately update Jenkins.

Summary

Red Hat Security Advisory: OpenShift Container Platform 4.10.56 security update

Severity

Critical

Scope

10 vulnerabilities in this advisory, including CVE-2023-27899.

CVE-2023-27899

A flaw was found in Jenkins. Jenkins creates a temporary file when a plugin is uploaded from an administrator’s computer. If these permissions are overly permissive, they may allow attackers with access to the Jenkins controller file system to read and write the file before it is installed in Jenkins, potentially resulting in arbitrary code execution.

Summary

Jenkins: Mehrere Schwachstellen

Severity

Mittel

Scope

9 vulnerabilities in this advisory, including CVE-2023-27899.

CVE-2023-27899

In Jenkins existieren mehrere Schwachstellen in unterschiedlichen Plugins und Komponenten. Dabei handelt es sich um ungenügende Eingabeüberprüfungen, unsichere Datei-Berechtigungen und unsichere Speicherung von Informationen. Ein Angreifer kann diese Schwachstellen ausnutzen, um Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, einen Cross-Site-Scripting-Angriff durchzuführen und Code auszuführen. Die erfolgreiche Ausnutzung einiger dieser Schwachstellen erfordert eine Benutzerinteraktion oder Anmeldung.
