## What is CVE-2017-10940?

CVE-2017-10940 is a high-severity vulnerability in Joyent Smart Data Center, published on 31 Oct 2017. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Joyent Smart Data Center prior to agentsshar@1.0.0-release-20160901-20160901T051624Z-g3fd5adf (e469cf49-4de3-4658-8419-ab42837916ad). An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the docker API. The process does not properly validate user-supplied data which can allow for the upload of arbitrary files. An attacker can leverage this vulnerability to execute arbitrary code under the context of root. Was ZDI-CAN-3853.

What it is: CVE-2017-10940 is a high-severity vulnerability in Joyent Smart Data Center, published on 31 Oct 2017. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-10940 in the wild and no public exploit code.

Affected product: Joyent Smart Data Center. 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.
