Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Remote Command Execution and Denial of Service Vulnerabilities
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 code execution or DoS via insufficient input validation.
Vulnerability
These vulnerabilities (CVE-2022-20888) exist in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers. They are due to insufficient validation of user fields within incoming HTTP packets. Affected versions are not specified, but all models listed are affected [1].
Exploitation
An authenticated remote attacker with valid Administrator credentials can exploit these vulnerabilities by sending a crafted HTTP request to the web-based management interface. The interface is accessible via LAN (cannot be disabled) or via WAN if remote management is enabled (disabled by default) [1].
Impact
Successful exploitation allows arbitrary command execution with root-level privileges or causes the device to restart unexpectedly, leading to a denial of service (DoS) condition [1].
Mitigation
Cisco has not released software updates to address these vulnerabilities. No workarounds are available as of the advisory date [1].
