'Name' => 'Symantec Altiris DS SQL Injection',
'Description'=> %q{
This module exploits a SQL injection flaw in Symantec Altiris Deployment Solution 6.8
to 6.9.164. The vulnerability exists on axengine.exe which fails to adequately sanitize
numeric input fields in "UpdateComputer" notification Requests. In order to spawn a shell,
several SQL injections are required in close succession, first to enable xp_cmdshell, then
retrieve the payload via TFTP and finally execute it. The module also has the capability
to disable or enable local application authentication. In order to work the target system
must have a tftp client available.
