Description

According to its self-reported version, Cisco Small Business RV Series Router Firmware is affected by an authentication bypass vulnerability due to improper session management on affected devices. An unauthenticated, remote attacker can exploit this, by sending a crafted HTTP request to the affected device, in order to bypass authentication and execute arbitrary commands with administrative privileges on an affected device.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
