## What is CVE-2024-51735?

CVE-2024-51735 is a high-severity cross-site scripting vulnerability in j3ssie osmedeus, published on 5 Nov 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

Osmedeus is a Workflow Engine for Offensive Security. Cross-site Scripting (XSS) occurs on the Osmedues web server when viewing results from the workflow, allowing commands to be executed on the server. When using a workflow that contains the summary module, it generates reports in HTML and Markdown formats. The default report is based on the `general-template.md` template.The contents of the files are read and used to generate the report. However, the file contents are not properly filtered, leading to XSS. This may lead to commands executed on the host as well. This issue is not yet resolved. Users are advised to add their own filtering or to reach out to the developer to aid in developing a patch.

Weakness: CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page), CWE-79 (Improper Neutralization of Input During Web Page Generation)

Affected packages and fixed versions:
- github.com/j3ssie/osmedeus (Go): affected all versions; no fix listed
- github.com/j3ssie/osmedeus (Go): affected all versions up to 4.6.4; no fix listed
- github.com/j3ssie/osmedeus (Go): affected all versions up to 4.6.4; 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.
