## What is CVE-2019-16017?

CVE-2019-16017 is a medium-severity vulnerability in Cisco Unified Customer Voice Portal (CVP), published on 23 Sep 2020. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

A vulnerability in the Operations, Administration, Maintenance and Provisioning (OAMP) OpsConsole Server for Cisco Unified Customer Voice Portal (CVP) could allow an authenticated, remote attacker to execute Insecure Direct Object Reference actions on specific pages within the OAMP application. The vulnerability is due to insufficient input validation on specific pages of the OAMP application. An attacker could exploit this vulnerability by authenticating to Cisco Unified CVP and sending crafted HTTP requests. A successful exploit could allow an attacker with administrator or read-only privileges to learn information outside of their expected scope. An attacker with administrator privileges could modify certain configuration details of resources outside of their defined scope, which could result in a denial of service (DoS) condition.

Weakness: CWE-20 (Improper Input Validation), CWE-264

Affected product: Cisco Unified Customer Voice Portal (CVP). 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.
