| 19 | + This module exploits a SQL injection flaw in Symantec Altiris Deployment Solution 6.8 |
| 20 | + to 6.9.164. The vulnerability exists on axengine.exe which fails to adequately sanitize |
| 21 | + numeric input fields in "UpdateComputer" notification Requests. In order to spawn a shell, |
| 22 | + several SQL injections are required in close succession, first to enable xp_cmdshell, then |
| 23 | + retrieve the payload via TFTP and finally execute it. The module also has the capability |
| 24 | + to disable or enable local application authentication. In order to work the target system |
| 25 | + must have a tftp client available. |
