In case you missed it there is a vulnerability in the CISCOIronport telnet service. Details can be found here http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120126-ironport
To mitigate the risk (if you can't upgrade just yet) is to switch off telnet on the device and use SSHto manage it instead.
