## What is CVE-2020-3150?

CVE-2020-3150 is a medium-severity missing authorization vulnerability in Cisco Rv110w Firmware, published on 16 Jul 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability in the web-based management interface of Cisco Small Business RV110W and RV215W Series Routers could allow an unauthenticated, remote attacker to download sensitive information from the device, which could include the device configuration. The vulnerability is due to improper authorization of an HTTP request. An attacker could exploit this vulnerability by accessing a specific URI on the web-based management interface of the router, but only after any valid user has opened a specific file on the device since the last reboot. A successful exploit would allow the attacker to view sensitive information, which should be restricted.

Weakness: CWE-863 (Incorrect Authorization), CWE-285 (Improper Authorization)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2020-3150 and fix it if it is affected.

What it is: CVE-2020-3150 is a medium-severity missing authorization vulnerability in Cisco Rv110w Firmware, published on 16 Jul 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2020-3150 in the wild and no public exploit code.

Affected product: Cisco Rv110w Firmware. 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.
