## What is CVE-2019-1879?

CVE-2019-1879 is a medium-severity command injection vulnerability in Cisco Unified Computing System, published on 20 Jun 2019. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability in the CLI of Cisco Integrated Management Controller (IMC) could allow an authenticated, local attacker to inject arbitrary commands that are executed with root privileges. The vulnerability is due to insufficient validation of user-supplied input at the CLI. An attacker could exploit this vulnerability by authenticating with the administrator password via the CLI of an affected device and submitting crafted input to the affected commands. A successful exploit could allow the attacker to execute arbitrary commands on the device with root privileges.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2019-1879 and fix it if it is affected.

What it is: CVE-2019-1879 is a medium-severity command injection vulnerability in Cisco Unified Computing System, published on 20 Jun 2019. 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-2019-1879 in the wild and no public exploit code.

Affected product: Cisco Unified Computing System. 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.
