Synopsis

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

Description

An authentication bypass vulnerability exists in the web-based management component of Cisco Identity Services Engine due to insufficient validation of user-supplied URL input. An authenticated, remote attacker can exploit this, by submitting specially crafted URL to an affected host, to modify parts of the device configuration. Successful exploitation could allow unauthorized devices onto the network or prevent authorized devices from accessing the network.

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