CVE-2024-47533 is a critical authentication bypass vulnerability in cobbler, published on 18 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description Cobbler, a Linux installation server that allows for rapid setup of network installation environments, has an improper authentication vulnerability starting in version 3.0.0 and prior to versions 3.2.3 and 3.3.7. `utils.get_shared_secret()` always returns `-1`, which allows anyone to connect to cobbler XML-RPC as user `''` password `-1` and make any changes. This gives anyone with network access to a cobbler server full control of the server. Versions 3.2.3 and 3.3.7 fix the issue.

What it is: CVE-2024-47533 is a critical authentication bypass vulnerability in cobbler, published on 18 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-47533 exists. Affected packages and fixed versions: - cobbler (PyPI): affected from 3.0.0; fixed in 3.2.3, 3.3.7 - cobbler (PyPI): affected from 3.0.0; fixed in 3.2.3 - cobbler (PyPI): affected from 3.0.0; fixed in 3.2.3 - cobbler (PyPI): affected from 3.3.0; fixed in 3.3.7 - cobbler (PyPI): affected from 3.3.0; fixed in 3.3.7 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.
