Cisco Small Business RV Series Routers Management Interface Multiple Vulnerabilities (cisco-sa-rv-overflow-ghZP68yj)

high Nessus Plugin ID 146266


The remote device is missing a vendor-supplied security patch.


According to its self-reported version, Cisco Small Business RV Series Router Firmware is affected by multiple vulnerabilities in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 Routers could allow an authenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly. These vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition. 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.
