## What is CVE-2019-15273?

CVE-2019-15273 is a medium-severity path traversal vulnerability in Cisco TelePresence TC Software, published on 16 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 CLI of Cisco TelePresence Collaboration Endpoint (CE) Software could allow an authenticated, local attacker to overwrite arbitrary files. The vulnerabilities are due to insufficient permission enforcement. An attacker could exploit these vulnerabilities by authenticating as the remote support user and submitting malicious input to specific commands. A successful exploit could allow the attacker to overwrite arbitrary files on the underlying filesystem. The attacker has no control over the contents of the data written to the file. Overwriting a critical file could cause the device to crash, resulting in a denial of service condition (DoS).

Weakness: CWE-20 (Improper Input Validation)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2019-15273 and fix it if it is affected.

What it is: CVE-2019-15273 is a medium-severity path traversal vulnerability in Cisco TelePresence TC Software, published on 16 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-2019-15273 in the wild and no public exploit code.

Affected product: Cisco TelePresence TC Software. 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.
