## What is CVE-2025-20305?

CVE-2025-20305 is a medium-severity vulnerability in Cisco Identity Services Engine, published on 5 Nov 2025. 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 ISE could allow an authenticated, remote attacker to obtain sensitive information from an affected device.

 This vulnerability exists because certain files lack proper data protection mechanisms. An attacker with read-only Administrator privileges could exploit this vulnerability by performing actions where the results should only be viewable to a high-privileged user. A successful exploit could allow the attacker to view passwords that are normally not visible to read-only administrators.

Weakness: CWE-1220 (Insufficient Granularity of Access Control)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-20305 and fix it if it is affected.

What it is: CVE-2025-20305 is a medium-severity vulnerability in Cisco Identity Services Engine, published on 5 Nov 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-20305 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.
