"Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV340 and RV345 Routers could 
allow an authenticated, remote attacker to inject and execute arbitrary commands on the underlying operating system of 
an affected device. These vulnerabilities are due to insufficient validation of user-supplied input. An attacker could 
exploit these vulnerabilities by sending malicious input to an affected device. A successful exploit could allow the 
attacker to execute arbitrary commands on the underlying Linux operating system of the affected device. To exploit 
these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
