Packages

|---|---|---|---|
| Maven | org.apache.commons:commons-vfs2 | < 2.10.0 | 2.10.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
Relative Path Traversal vulnerability in Apache Commons VFS before 2.10.0.
The FileObject API in Commons VFS has a 'resolveFile' method that
takes a 'scope' parameter. Specifying 'NameScope.DESCENDENT' promises that "an exception is thrown if the resolved file is not a descendent of
the base file". However, when the path contains encoded ".."
characters (for example, "%2E%2E/bar.txt"), it might return file objects that are not
a descendent of the base file, without throwing an exception.
This issue affects Apache Commons VFS: before 2.10.0.
Users are recommended to upgrade to version 2.10.0, which fixes the issue.
