Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence

Multiple vulnerabilities in Cisco Small Business RV160, RV260, RV340, and RV345 Series Routers could allow remote attackers to execute arbitrary code or commands, elevate privileges, bypass authentication mechanisms, deploy unsigned software, or cause denial of service conditions.

MitigationApply the relevant Cisco firmware updates for the RV series routers once available; restrict management interface access to trusted networks and monitor for indicators of compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify your router model
    Log into the router web interface or check the physical device label to determine if it is an RV340, RV340w, RV345, or RV345p model
    Affected if The router is one of these four models
  2. Check the firmware version
    In the router web interface, navigate to Administration > Firmware Upgrade or check the System Summary page to view the currently installed firmware version
    Affected if The installed firmware version is 1.0.03.24 or lower
  3. Verify management interface exposure
    Check router firewall rules or upstream network configuration to determine if the router management interface (HTTP/HTTPS for web UI, SSH, or VPN) is accessible from untrusted networks
    Affected if The management interface is exposed to the internet or untrusted networks

You are affected if you have an RV340, RV340w, RV345, or RV345p router running firmware version 1.0.03.24 or lower, especially if the management interface is externally accessible.
