        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.
