Path traversal vulnerability on Windows in Jenkins
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.jenkins-ci.main:jenkins-core | < 2.303.2 | 2.303.2 |
| Maven | org.jenkins-ci.main:jenkins-core | >= 2.304, < 2.315 | 2.315 |
Details
As written in the advisory (Markdown source, shown as plain text).
The file browser for workspaces, archived artifacts, and `userContent/` in Jenkins 2.314 and earlier, LTS 2.303.1 and earlier may interpret some paths to files as absolute on Windows.
This results in a path traversal vulnerability allowing attackers with Overall/Read permission (Windows controller) or Job/Workspace permission (Windows agents) to obtain the contents of arbitrary files.\n\nThe file browser in Jenkins 2.315, LTS 2.303.2 refuses to serve files that would be considered absolute paths.
