## What is CVE-2019-1807?

CVE-2019-1807 is a high-severity authentication bypass vulnerability in Cisco Umbrella, published on 3 May 2019. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

A vulnerability in the session management functionality of the web UI for the Cisco Umbrella Dashboard could allow an authenticated, remote attacker to access the Dashboard via an active, user session. The vulnerability exists due to the affected application not invalidating an existing session when a user authenticates to the application and changes the users credentials via another authenticated session. An attacker could exploit this vulnerability by using a separate, authenticated, active session to connect to the application through the web UI. A successful exploit could allow the attacker to maintain access to the dashboard via an authenticated user's browser session. Cisco has addressed this vulnerability in the Cisco Umbrella Dashboard. No user action is required.

Weakness: CWE-384 (Session Fixation)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2019-1807 and fix it if it is affected.

What it is: CVE-2019-1807 is a high-severity authentication bypass vulnerability in Cisco Umbrella, published on 3 May 2019. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2019-1807 in the wild and no public exploit code.

Affected product: Cisco Umbrella. 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.
