CVE-2022-20880: 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

Cisco disclosed flaws in several Small Business RV routers that let a logged-in administrator remotely run commands as root or crash the device. The attacker needs valid Administrator credentials, which lowers likelihood, but root access and no Cisco software fix make exposed management interfaces a meaningful business risk.

Executive priority

Treat as a targeted administrative-control risk. It is not known to be actively exploited from the provided sources, but successful abuse gives root-level device control or outage, and Cisco has not provided a patch.

Technical view

The issue affects the web-based management interface of Cisco RV110W, RV130, RV130W, and RV215W routers. Insufficient validation of user fields in incoming HTTP packets can permit authenticated remote command execution or denial of service. Cisco states no software updates address these vulnerabilities.

Likely exposure

Exposure is most likely where affected routers are still deployed and their web management interface is reachable by administrators or networks where admin credentials could be abused. The source bundle does not confirm affected firmware ranges beyond the named router models.

Exploitation context

The sources require valid Administrator credentials and a crafted request to the web management interface. KEV status is false, and the provided sources do not report active exploitation or public weaponization.

Researcher notes

Key constraints are authenticated remote access and high privileges. The CVSS 3.1 score is 4.7 with AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L. Evidence is limited to Cisco and CVE records; no patched version or exploit-in-the-wild evidence is provided.

Mitigation direction

  • Identify and prioritize all RV110W, RV130, RV130W, and RV215W routers.
  • Review Cisco’s advisory for current vendor guidance before deciding remediation.
  • Restrict management interface access to trusted administrative networks only.
  • Rotate and tightly control Administrator credentials on affected devices.
  • Plan replacement or removal where risk cannot be mitigated without a vendor patch.

Validation and detection

  • Confirm whether any named Cisco RV router models remain in production.
  • Verify management interfaces are not broadly reachable from untrusted networks.
  • Review who has Administrator credentials for affected devices.
  • Check device logs for unexpected restarts or suspicious admin activity.
  • Document compensating controls because Cisco lists no software update.
