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

CVE-2022-20889

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.

Multiple vulnerabilities in Cisco Small Business RV series routers allow authenticated remote attackers to execute arbitrary code or cause DoS via crafted HTTP requests.

Vulnerability

Multiple vulnerabilities exist in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers. The issues stem from insufficient validation of user-supplied fields within incoming HTTP packets. An attacker can exploit these by sending a specially crafted request to the management interface. Affected devices run firmware versions prior to any fix; Cisco has not released software updates addressing these vulnerabilities [1].

Exploitation

An attacker must have valid Administrator credentials for the targeted device. The web-based management interface is accessible over a LAN connection (which cannot be disabled) or over a WAN connection if the remote management feature is enabled (disabled by default). The attacker sends a crafted HTTP request to the management interface, triggering the insufficient validation [1].

Impact

Successful exploitation allows the attacker to execute arbitrary commands on the device with root-level privileges or to cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. The attacker gains full control over the router or disrupts its operation [1].

Mitigation

Cisco has not released software updates to address these vulnerabilities, and no workarounds are available. The affected routers are end-of-life; Cisco recommends upgrading to a supported product. As a temporary measure, disable remote management if it is enabled and restrict LAN access to trusted administrators [1].
