## What is CVE-2017-12223?

CVE-2017-12223 is a medium-severity code injection vulnerability in Cisco IR800 Integrated Services Router, published on 7 Sep 2017. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability in the ROM Monitor (ROMMON) code of Cisco IR800 Integrated Services Router Software could allow an unauthenticated, local attacker to boot an unsigned Hypervisor on an affected device and compromise the integrity of the system. The vulnerability is due to insufficient sanitization of user input. An attacker who can access an affected router via the console could exploit this vulnerability by entering ROMMON mode and modifying ROMMON variables. A successful exploit could allow the attacker to execute arbitrary code and install a malicious version of Hypervisor firmware on an affected device. Cisco Bug IDs: CSCvb44027.

Weakness: CWE-20 (Improper Input Validation)

Check this codebase for CVE-2017-12223 and fix it if it is affected.

What it is: CVE-2017-12223 is a medium-severity code injection vulnerability in Cisco IR800 Integrated Services Router, published on 7 Sep 2017. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-12223 in the wild and no public exploit code.

Affected product: Cisco IR800 Integrated Services Router. 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.
