Cisco Small Business RV110W, RV130, RV130W, and RV215W Series Routers Management Interface Vulnerabilities

Vulnerability

Multiple command injection vulnerabilities exist in the web-based management interface of Cisco RV110W, RV130, RV130W, and RV215W Series Routers. These flaws allow an authenticated attacker with administrative privileges to execute arbitrary commands on the underlying operating system. The vulnerabilities affect firmware versions prior to the fixed releases indicated in the Cisco advisory [1].

Exploitation

An attacker must have valid administrative credentials and network access to the router's web-based management interface. No additional user interaction is required. The attacker can send specially crafted HTTP requests to the management interface to trigger command injection.

Impact

Successful exploitation grants the attacker arbitrary command execution at the root privilege level. This can lead to full compromise of the device, including data exfiltration, installation of malicious software, and further network attacks.

Mitigation

Cisco has released free software updates to address these vulnerabilities. Customers should upgrade their firmware to the fixed versions as specified in the advisory [1]. No workarounds are available; disabling the management interface on WAN side is recommended as a best practice.
