OVERVIEW:

       security vulnerability when configured to accept Clientless SSL VPN
       connections.


IMPACT:

       If a user is tricked into visiting a malicious CIFS or FTP site, 
       an attacker may be able to procure user credentials via phishing
       or spoofing attacks, due to insufficient warnings and restrictions.
       
       This vulnerability affects Cisco ASA Adaptive Security Appliance 
       Software versions prior to 8.0.4(34), 8.1.2(25) and 8.2.1(3). [1]
