## What is CVE-2020-3467?

CVE-2020-3467 is a high-severity missing authorization vulnerability in Cisco Identity Services Engine, published on 8 Oct 2020. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to modify parts of the configuration on an affected device. The vulnerability is due to improper enforcement of role-based access control (RBAC) within the web-based management interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to modify parts of the configuration. The modified configuration could either allow unauthorized devices onto the network or prevent authorized devices from accessing the network. To exploit this vulnerability, an attacker would need valid Read-Only Administrator credentials.

Weakness: CWE-863 (Incorrect Authorization)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2020-3467 and fix it if it is affected.

What it is: CVE-2020-3467 is a high-severity missing authorization vulnerability in Cisco Identity Services Engine, published on 8 Oct 2020. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2020-3467 in the wild and no public exploit code.

Affected product: Cisco Identity Services Engine. 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.
