## What is CVE-2024-7923?

CVE-2024-7923 is a critical authentication bypass vulnerability in Redhat Satellite, published on 4 Sep 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An authentication bypass vulnerability has been identified in Pulpcore when deployed with Gunicorn versions prior to 22.0, due to the puppet-pulpcore configuration. This issue arises from Apache's mod_proxy not properly unsetting headers because of restrictions on underscores in HTTP headers, allowing authentication through a malformed header. This flaw impacts all active Satellite deployments (6.13, 6.14 and 6.15) which are using Pulpcore version 3.0+ and could potentially enable unauthorized users to gain administrative access.

Weakness: CWE-287 (Improper Authentication)

Check this codebase for CVE-2024-7923 and fix it if it is affected.

What it is: CVE-2024-7923 is a critical authentication bypass vulnerability in Redhat Satellite, published on 4 Sep 2024. 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-2024-7923 in the wild and no public exploit code.

Affected product: Redhat Satellite. 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.
