## What is CVE-2022-45378?

CVE-2022-45378 is a critical missing authorization vulnerability in Apache SOAP, published on 14 Nov 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In the default configuration of Apache SOAP, an RPCRouterServlet is available without authentication. This gives an attacker the possibility to invoke methods on the classpath that meet certain criteria. Depending on what classes are available on the classpath this might even lead to arbitrary remote code execution. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

Affected packages and fixed versions:
- soap:soap (Maven): affected from 0.0.0; no fix listed
- soap:soap (Maven): affected from 0.0.0; no fix listed

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.
