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

CVE-2022-20884

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

Vulnerability

The vulnerabilities affect the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers [1]. They are due to insufficient validation of user fields within incoming HTTP packets. An attacker with valid Administrator credentials can send a crafted request to trigger the flaw. No software updates have been released by Cisco to address these issues [1].

Exploitation

An attacker must have valid Administrator credentials for the affected device [1]. The web-based management interface is accessible over LAN (cannot be disabled) or over WAN if remote management is enabled (disabled by default) [1]. The attacker sends a specially crafted HTTP request to the interface, exploiting the insufficient field validation to cause arbitrary command execution or device restart.

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 [1].

Mitigation

Cisco has not released software updates to address these vulnerabilities. No workarounds are available [1]. Affected devices may be end-of-life; organizations should consult Cisco's advisory and consider migration to supported models [1].
