high Nessus Plugin ID 143157

Language:

Synopsis

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

Description

A denial of service (DoS) vulnerability exists in Cisco IOS Access Points due to a lack of complete error handling condition for client authentication requests sent to a targeted interface configured for FT. An unauthenticated, adjacent attacker can exploit this issue, by sending crafted authentication request traffic to the targeted interface, to cause the device to restart.

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

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCvg957452.
