## What is CVE-2016-3173?

CVE-2016-3173 is a medium-severity cross-site scripting vulnerability in Open-Xchange Open-Xchange Appsuite, published on 15 Dec 2016. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

An issue was discovered in Open-Xchange OX AppSuite before 7.8.0-rev27. The aria-label parameter of tiles at the Portal can be used to inject script code. Those labels use the name of the file (e.g. an image) which gets displayed at the portal application. Using script code at the file name leads to script execution. Malicious script code can be executed within a user's context. This can lead to session hijacking or triggering unwanted actions via the web interface (sending mail, deleting data etc.). Users actively need to add a file to the portal to enable this attack. In case of shared files however, a internal attacker may modify a previously embedded file to carry a malicious file name. Furthermore this vulnerability can be used to persistently execute code that got injected by a temporary script execution vulnerability.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Check this codebase for CVE-2016-3173 and fix it if it is affected.

What it is: CVE-2016-3173 is a medium-severity cross-site scripting vulnerability in Open-Xchange Open-Xchange Appsuite, published on 15 Dec 2016. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2016-3173 in the wild and no public exploit code.

Affected product: Open-Xchange Open-Xchange Appsuite. 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.
