## What is CVE-2023-7273?

CVE-2023-7273 is a medium-severity vulnerability in Kiteworks OwnCloud, published on 1 Oct 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Cross site request forgery in Kiteworks OwnCloud allows an unauthenticated attacker to forge requests.
If a request has no Authorization header, it is created with an empty string as value by a rewrite rule. The CSRF check is done by comparing the header value to null, meaning that the existing CSRF check is bypassed in this case. An attacker can, for example, create a new administrator account if the request is executed in the browser of an authenticated victim.

Weakness: CWE-352 (Cross-Site Request Forgery)

Affected product: Kiteworks OwnCloud. 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.
