CA BrightStor ARCserve Backup Mediasvr.exe vulnerability

["Williams, James K" <James.Williams () ca com>]

CA is aware that functional exploit code was publicized on 
March 30, 2007 for a CA BrightStor ARCserve Backup Mediasvr.exe 
vulnerability. 

We have verified that a high risk vulnerability does exist and we 
are now working on a patch to address the issue. 

CA recommends that BrightStor ARCserve Backup users implement the 
following temporary workaround to mitigate the vulnerability: 

1) Rename the "mediasvr.exe" file to a non-functional file name, 
   such as "mediasvc.exe.disable".

2) Then restart the CA BrightStor Tape Engine service.

This will disable the command line functionality in the product 
(i.e. command line utilities such as ca_backup, ca_restore, 
ca_merge, ca_qmgr, ca_scan, etc will not work).

After we have completed our analysis of the issue, we will post 
an update and patches on the CA SupportConnect website. If 
additional information is required, please contact CA Technical 
Support at http://supportconnect.ca.com.
