## What is CVE-2019-15246?

CVE-2019-15246 is a high-severity code injection vulnerability in Cisco SPA112 2-Port Phone Adapter, 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 Cisco SPA100 Series Analog Telephone Adapters (ATAs) could allow an authenticated, adjacent attacker to execute arbitrary code with elevated privileges. The vulnerabilities are due to improper validation of user-supplied input to the web-based management interface. An attacker could exploit these vulnerabilities by authenticating to the web-based management interface and sending crafted requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code with elevated privileges. Note: The web-based management interface is enabled by default.

Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2019-15246 and fix it if it is affected.

What it is: CVE-2019-15246 is a high-severity code injection vulnerability in Cisco SPA112 2-Port Phone Adapter, 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-2019-15246 in the wild and no public exploit code.

Affected product: Cisco SPA112 2-Port Phone Adapter. 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.
