Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Remote Command Execution and Denial of Service Vulnerabilities

CVE-2022-20895

Description

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.

AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Authenticated remote command injection in Cisco Small Business RV Series routers; no fix available, allowing root-level RCE or DoS via crafted HTTP requests.

Vulnerability

The web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers is affected by multiple vulnerabilities that allow authenticated command injection. These vulnerabilities stem from insufficient validation of user-supplied fields within incoming HTTP packets. An attacker with valid Administrator credentials can exploit them by sending a crafted request to the management interface. The vulnerabilities affect all firmware versions of the listed routers; Cisco has not released software updates addressing them. [1]

Exploitation

An attacker must have valid Administrator credentials on the affected device and network access to the web-based management interface. This interface is accessible via LAN (and cannot be disabled) or via WAN if remote management is enabled (disabled by default). The attacker sends a specially crafted HTTP request to the interface. No user interaction is required beyond authentication. The advisory does not provide further detail on the exact request structure. [1]

Impact

Successful exploitation allows an attacker to execute arbitrary commands on the affected device with root-level privileges or to cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. This can lead to full compromise of the router's configuration and network traffic, or disruption of network connectivity. [1]

Mitigation

Cisco has not released software updates to address these vulnerabilities. No workarounds are available. The recommended mitigation is to restrict access to the management interface by disabling remote management (WAN) and ensuring the LAN interface is only accessible to trusted administrators. Affected devices are not listed as End-of-Life (EOL) at the time of publication but are considered end of support for patching purposes according to Cisco's advisory. The vulnerabilities are not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog as of the publication date. [1]
