CVSS: 7.0EPSS: 0%CPEs: 2EXPL: 0CVE-2023-27899 – Jenkins: Temporary plugin file created with insecure permissions
https://notcve.org/view.php?id=CVE-2023-27899
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. 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. • https://www.jenkins.io/security/advisory/2023-03-08/#SECURITY-2823 https://access.redhat.com/security/cve/CVE-2023-27899 https://bugzilla.redhat.com/show_bug.cgi?id=2177626 • CWE-378: Creation of Temporary File With Insecure Permissions CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2022-2048
In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests. En la implementación del servidor Eclipse Jetty HTTP/2, cuando es encontrada una petición HTTP/2 no válida, el manejo de errores presenta un error que puede terminar por no limpiar apropiadamente las conexiones activas y los recursos asociados. Esto puede conllevar a un escenario de denegación de servicio en el que no queden recursos suficientes para procesar las peticiones buenas A flaw was found in the Eclipse Jetty http2-server package. This flaw allows an attacker to cause a denial of service in the server via HTTP/2 requests. • http://www.openwall.com/lists/oss-security/2022/09/09/2 https://github.com/eclipse/jetty.project/security/advisories/GHSA-wgmr-mf83-7x4j https://lists.debian.org/debian-lts-announce/2022/08/msg00011.html https://security.netapp.com/advisory/ntap-20220901-0006 https://www.debian.org/security/2022/dsa-5198 https://access.redhat.com/security/cve/CVE-2022-2048 https://bugzilla.redhat.com/show_bug.cgi?id=2116952 • CWE-410: Insufficient Resource Pool CWE-664: Improper Control of a Resource Through its Lifetime •
