CVSS: 4.3EPSS: 0%CPEs: 2EXPL: 0CVE-2023-27902 – Jenkins: Workspace temporary directories accessible through directory browser
https://notcve.org/view.php?id=CVE-2023-27902
Jenkins 2.393 and earlier, LTS 2.375.3 and earlier shows temporary directories related to job workspaces, which allows attackers with Item/Workspace permission to access their contents. A flaw was found in Jenkins. Jenkins uses temporary directories adjacent to workspace directories, usually with the @tmp name suffix, to store temporary files related to the build. In pipelines, these temporary directories are adjacent to the current working directory when operating in a subdirectory of the automatically allocated workspace. Jenkins-controlled processes, like SCMs, may store credentials in these directories. • https://www.jenkins.io/security/advisory/2023-03-08/#SECURITY-1807 https://access.redhat.com/security/cve/CVE-2023-27902 https://bugzilla.redhat.com/show_bug.cgi?id=2177630 • CWE-266: Incorrect Privilege Assignment •

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 •
