What to do
- Update Plexus-utils to 3.0.24 or a later version.
- Update Integration Camel K to 1.10.1 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A flaw was found in codeplex-codehaus. A directory traversal attack (also known as path traversal) aims to access files and directories stored outside the intended folder. By manipulating files with "dot-dot-slash (../)" sequences and their variations or by using absolute file paths, it may be possible to access arbitrary files and directories stored on the file system, including application source code, configuration, and other critical system files.

The underlying weakness: Improper Limitation of a Pathname to a Restricted Directory
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
How developers prevent this class of flaw
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
