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
The web management interface on the Cisco RV110W firewall with firmware 1.2.0.9 and earlier, RV215W router with firmware 1.1.0.5 and earlier, and CVR100W router with firmware 1.0.1.19 and earlier does not prevent replaying of modified authentication requests, which allows remote attackers to obtain administrative access by leveraging the ability to intercept requests, aka Bug IDs CSCul94527, CSCum86264, and CSCum86275.

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 · high confidence

The web management interface on Cisco RV110W, RV215W, and CVR100W devices lacks protection against authentication replay attacks. The interface does not implement anti-replay mechanisms such as session tokens, nonces, or timestamp validation, allowing an attacker who intercepts a valid authentication request to replay it and gain administrative access without knowing credentials.

MitigationUpgrade firmware to versions newer than 1.2.0.9 (RV110W), 1.1.0.5 (RV215W), or 1.0.1.19 (CVR100W). Until patched, restrict web management interface access to trusted networks only and disable remote management on WAN interfaces if not needed.

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 device model and firmware version
    Access the device web interface or check the administrative console to view the device status or system information page. Look for the model number (RV110W, RV215W, or CVR100W) and firmware version displayed.
    Affected if The device is a Cisco RV110W, RV215W, or CVR100W with firmware version 1.2.0.9 or lower for RV110W, 1.1.0.5 or lower for RV215W, or 1.0.1.19 or lower for CVR100W.
  2. Confirm web management interface is enabled
    Navigate to the device web interface Administration or Management settings. Look for options named 'Web Management', 'HTTP/HTTPS Management', or 'Remote Management'. Verify the status shows it is enabled.
    Affected if The web management interface is enabled on the device.
  3. Check if remote WAN access is permitted
    In the device web interface, examine the remote management settings. Look for options controlling access from WAN or external networks. Determine if HTTP or HTTPS management is allowed from outside the local network.
    Affected if Remote (WAN) access to the web management interface is permitted.
  4. Review authentication logs for replay patterns
    Access the device logs or monitoring section. Search for multiple successful administrative logins from the same source IP address occurring within a very short time window (seconds apart), which could indicate replay attacks.
    Affected if Multiple identical authentication requests or simultaneous logins from the same source are observed in the logs.

The device is affected if it is a Cisco RV110W, RV215W, or CVR100W with firmware at or below the affected version thresholds and the web management interface is enabled and accessible.

Interim mitigation

Upgrade firmware to versions newer than 1.2.0.9 (RV110W), 1.1.0.5 (RV215W), or 1.0.1.19 (CVR100W). Until patched, restrict web management interface access to trusted networks only and disable remote management on WAN interfaces if not needed.

Recommended fix Moderate confidence

RV110W: upgrade to firmware 1.2.1.0 or later; RV215W: upgrade to firmware 1.1.0.6 or later; CVR100W: upgrade to firmware 1.0.1.20 or later

  1. 1. Identify the exact model number (RV110W, RV215W, or CVR100W) of your Cisco device
  2. 2. Access the device's web management interface
  3. 3. Navigate to Administration > Firmware Upgrade or similar menu
  4. 4. Download the appropriate fixed firmware from Cisco's official support site
  5. 5. Upload and apply the firmware update to the device
  6. 6. After reboot, verify the new firmware version is installed
  7. 7. Change administrative passwords as a precaution since authentication was compromised
Caveat These are older end-of-life devices; ensure compatibility with your network before upgrading; backup configuration before firmware update
