Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Management Interface 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 or cause an affected device to restart unexpectedly. The vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (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 code execution and denial-of-service vulnerabilities in Cisco Small Business RV series routers due to improper input validation in the web-based management interface.
Vulnerability
The web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers contains multiple vulnerabilities due to improper validation of user-supplied input. An authenticated, remote attacker can exploit these by sending crafted HTTP requests to the device. All firmware versions of these models are affected. Cisco has not released software updates to address these issues [1].
Exploitation
An attacker must have valid administrator credentials for the affected device. The web-based management interface is accessible via a local LAN connection (which cannot be disabled) or via the WAN if the remote management feature is enabled (disabled by default). With credentials, the attacker sends specially crafted HTTP requests to trigger the vulnerability [1].
Impact
Successful exploitation allows the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition. This gives full control over the device and potential network access [1].
Mitigation
Cisco has not released software updates that address these vulnerabilities, and no workarounds are available. If remote management is enabled, disabling it reduces the attack surface, but the LAN interface remains exposed. Affected devices may be end-of-life; users should consider upgrading to supported models [1].
