OVERVIEW:

       Cisco has confirmed a security vulnerability in the IronPort AsyncOS.


IMPACT:

       The vendor has provided the following details regarding this
       vulnerability:

       "Cisco IronPort AsyncOS contains a cross-site scripting vulnerability 
       that could allow an unauthenticated, remote attacker to execute 
       arbitrary script code in the user's browser.

       The vulnerability exists in the login page of the Spam Quarantine 
       feature. An unauthenticated, remote attacker could exploit this 
       vulnerability by creating a malicious link and convincing a targeted 
       user to follow it. If the user clicks the link, the attacker could 
       execute arbitrary script code in the user's browser in the security 
       context of the affected site.

       A proof-of-concept URL is publicly available.

       Cisco has confirmed this vulnerability and updated software is 
       available." [1]


MITIGATION:

       Cisco have released a fix for this vulnerability and states:

       "Administrators can apply fixes by using the upgrade command from the 
       command line interface, or by using the System Administrator tab of 
       the graphical user interface (GUI) to select the System Upgrade option. 
       In either case, version 6.5.2 contains the fix." [1]
