Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Management Interface Remote Command Execution Vulnerability

Vulnerability

The vulnerability exists in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers. It is due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this by sending crafted HTTP requests to the affected device. All firmware versions prior to the fixed releases are affected [1].

Exploitation

An attacker does not need any authentication or prior access to the device. The exploitation requires network connectivity to the web-based management interface of the router. The attacker sends specially crafted HTTP requests to the vulnerable interface, which triggers the improper input validation leading to code execution [1].

Impact

Successful exploitation allows the attacker to execute arbitrary code as the root user on the underlying operating system. This gives the attacker full control over the affected device, including the ability to modify configuration, intercept traffic, and launch further attacks [1].

Mitigation

Cisco has released free software updates to address this vulnerability. Customers are advised to upgrade to the fixed firmware versions specified in the Cisco Security Advisory [1]. No workarounds are available. The advisory provides detailed instructions for obtaining and installing the updates [1].
