CVE-2019-13941 is a high-severity vulnerability in Siemens AG OZW672, published on 11 Feb 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability has been identified in OZW672 (All versions < V10.00), OZW772 (All versions < V10.00). Vulnerable versions of OZW Web Server use predictable path names for project files that legitimately authenticated users have created by using the application's export function. By accessing a specific uniform resource locator on the web server, a remote attacker could be able to download a project file without prior authentication. The security vulnerability could be exploited by an unauthenticated attacker with network access to the affected system. No user interaction is required to exploit this security vulnerability. Successful exploitation of the security vulnerability compromises the confidentiality of the targeted system.

Check this codebase for CVE-2019-13941 and fix it if it is affected.

What it is: CVE-2019-13941 is a high-severity vulnerability in Siemens AG OZW672, published on 11 Feb 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-13941 in the wild and no public exploit code.

Affected product: Siemens AG OZW672. 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.
