Cisco Cisco Web Security Appliance S690 Release Notes

Previously, the Web Proxy continually restarted when an IronPort Data Security Policy 
contained regular expressions with some special characters for file names to block. This no 
longer occurs. [Defect ID: 45785] 

Previously, an application fault occurred when a Web Security appliance user full name 
included some special characters. This no longer occurs. Now, when the full name of the 
appliance user contains one of the following characters, it displays a warning message 
instead: 

: @ !

 

[Defect ID: 47888] 

Previously, when FTP Proxy authentication was enabled, native FTP requests from the Filezilla 
FTP client were erroneously allowed even when the user supplied no or incorrect 
authentication credentials. This no longer occurs. [Defect ID: 49087] 

Previously, IronPort Data Security Filters did not block upload requests to sites that include 
the path with the file name in the upload request, such as Virgin Mail. This no longer occurs. 
Now, the upload requests are blocked as configured in the IronPort Data Security Policies. 
[Defect ID: 49326] 

Previously, the Web Proxy generated a core file when an FTP client issued the QUIT 
command after being idle for awhile. This no longer occurs. [Defect ID: 49469] 

Previously, the calendar file types of VCS and ICS were erroneously recognized as the 
“application/x-awk” MIME type. This no longer occurs. Now, these file types are recognized 
and matched as the “text/x-vcalendar” MIME type. [Defect ID: 49639]
