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

CVE-2022-20896

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 attacker can execute arbitrary commands or cause DoS on multiple Cisco Small Business RV routers via crafted HTTP requests due to insufficient input validation.

Vulnerability

The web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers contains multiple vulnerabilities due to insufficient validation of user fields within incoming HTTP packets [1]. An authenticated attacker can exploit these via crafted requests. Affected devices include all firmware versions prior to any fixes; no software updates have been released [1].

Exploitation

An attacker with valid Administrator credentials can send a crafted HTTP request to the web-based management interface [1]. The interface is accessible via LAN connection (cannot be disabled) or via WAN if remote management is enabled (disabled by default). No user interaction is required beyond the authenticated session. The attacker must craft a malicious payload in the request parameters.

Impact

Successful exploitation allows arbitrary command execution with root-level privileges, enabling full compromise of the device. Alternatively, the attacker can cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition [1]. Both outcomes are possible depending on the specific vulnerability triggered.

Mitigation

Cisco has not released software updates that address these vulnerabilities [1]. There are no workarounds. Affected products may be end-of-life; Cisco recommends upgrading to non-vulnerable models where available. As of the advisory date (July 2022), no patches exist [1].
