Synopsis

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

Description

Multiple vulnerabilities in the web-based user interface of certain Cisco Small Business Series Switches could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or execute arbitrary code with root privileges on an affected device. These vulnerabilities are due to improper validation of requests that are sent to the web interface.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
