## What is CVE-2023-4760?

CVE-2023-4760 is a high-severity path traversal vulnerability in Eclipse RAP, published on 21 Sep 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

In Eclipse RAP versions from 3.0.0 up to and including 3.25.0, Remote Code Execution is possible on Windows when using the FileUpload component.

The reason for this is a not completely secure extraction of the file name in the FileUploadProcessor.stripFileName(String name) method. As soon as this finds a / in the path, everything before it is removed, but potentially \ (backslashes) coming further back are kept.

For example, a file name such as /..\..\webapps\shell.war can be used to upload a file to a Tomcat server under Windows, which is then saved as ..\..\webapps\shell.war in its webapps directory and can then be executed.

Weakness: CWE-23 (Relative Path Traversal), CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Check this codebase for CVE-2023-4760 and fix it if it is affected.

What it is: CVE-2023-4760 is a high-severity path traversal vulnerability in Eclipse RAP, published on 21 Sep 2023. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-4760 in the wild and no public exploit code.

Affected product: Eclipse RAP. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
