CVE-2022-20910: Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Remote Command Execution and Denial of Service Vulnerabilities

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device or cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient validation of user fields within incoming HTTP packets. An attacker could exploit these vulnerabilities by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device with root-level privileges or to cause the device to restart unexpectedly, resulting in a DoS condition. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has not released software updates that address these vulnerabilities.

Security readout for executives and security teams

Plain-English summary

This affects older Cisco Small Business RV routers. An attacker who already has valid Administrator credentials could abuse the web management interface to run commands as root or crash the device. Cisco states it has not released software updates for these vulnerabilities.

Executive priority

Treat this as a targeted infrastructure hygiene issue, not an emergency based on current sources. Because no Cisco software fix is listed, prioritize exposure reduction, credential control, and replacement planning for affected routers.

Technical view

CVE-2022-20910 covers multiple web-based management interface flaws in Cisco RV110W, RV130, RV130W, and RV215W routers. Insufficient validation of user fields in incoming HTTP packets can permit authenticated remote command execution with root privileges or denial of service through unexpected restart. Exploitation requires valid Administrator credentials.

Likely exposure

Exposure is most likely where affected RV routers remain deployed and their web management interface is reachable by administrators or broader networks. Risk increases if Administrator credentials are weak, shared, reused, or compromised.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation is remote but requires high privileges: valid Administrator credentials on the affected device. Cisco reported no software updates addressing the issue.

Researcher notes

Evidence supports authenticated remote command execution and denial of service via HTTP field validation flaws in the management interface. The CVSS score is 4.7 because Administrator credentials are required, but successful exploitation can reach root-level command execution. No public source in the bundle confirms exploitation in the wild.

Mitigation direction

  • Check Cisco advisory for current vendor guidance and lifecycle options.
  • Inventory and prioritize replacement of affected RV110W, RV130, RV130W, and RV215W routers.
  • Restrict web management access to trusted administrator networks where possible.
  • Review and rotate Administrator credentials for affected devices.
  • Monitor Cisco and CVE sources for any updated remediation guidance.

Validation and detection

  • Identify deployed Cisco RV110W, RV130, RV130W, and RV215W routers.
  • Confirm whether web management interfaces are reachable from untrusted networks.
  • Verify that Administrator accounts are necessary, unique, and controlled.
  • Check whether each device is still supported or has replacement plans.
  • Review CISA KEV and vendor sources for any exploitation-status change.
