## What is CVE-2019-12674?

CVE-2019-12674 is a high-severity vulnerability in Cisco Secure Firewall Threat Defense, published on 2 Oct 2019. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Multiple vulnerabilities in the multi-instance feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to escape the container for their FTD instance and execute commands with root privileges in the host namespace. These vulnerabilities are due to insufficient protections on the underlying filesystem. An attacker could exploit these vulnerabilities by modifying critical files on the underlying filesystem. A successful exploit could allow the attacker to execute commands with root privileges within the host namespace. This could allow the attacker to impact other running FTD instances.

Weakness: CWE-116 (Improper Encoding or Escaping of Output), CWE-216 (DEPRECATED: Containment Errors (Container Errors))

Check this codebase for CVE-2019-12674 and fix it if it is affected.

What it is: CVE-2019-12674 is a high-severity vulnerability in Cisco Secure Firewall Threat Defense, published on 2 Oct 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-2019-12674 in the wild and no public exploit code.

Affected product: Cisco Secure Firewall Threat Defense. 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.
