According to its self-reported version, Cisco Small Business RV Series Router Firmware is affected by an information disclosure vulnerability in the web-based management interface due to improper authorization of HTTP requests. An unauthenticated, remote attacker can exploit this, by sending crafted HTTP requests to the web-based management interface, in order to view information displayed in the web-based management interface without authentication.
Please see the included Cisco BID(s) 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.
