Cisco Small Business RV016, RV042, RV042G, and RV082 Routers Arbitrary Command Execution Vulnerability

A vulnerability in the web-based management interface of certain Cisco Small Business RV Series Routers could allow an authenticated, remote attacker to execute arbitrary commands with root privileges. The attacker must have either a valid credential or an active session token.

The vulnerability is due to lack of input validation of the HTTP payload. An attacker could exploit this vulnerability by sending a malicious HTTP request to the web-based management interface of the targeted device. A successful exploit could allow the attacker to execute commands with root privileges.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
