Summary
Cisco Catalyst Switches running Cisco IOS Software releases prior to
15.2(2)E1 may allow an unauthenticated, remote attacker to retrieve version
information about the software release running on the device by accessing the
Network Mobility Services Protocol (NMSP) port.
The vulnerability is due to a failure to properly secure NMSP with
authentication, which has been made standard in Cisco IOS Software releases
15.2(2)E1 and later. An attacker could exploit earlier software releases to
map the network and gather information for further attacks.
Cisco has released software updates that address this vulnerability.
Workarounds that address this vulnerability are not available.
