| 17 | + This module exploits a code execution flaw in Lexmark MarkVision Enterprise before 2.1. A |
| 18 | + directory traversal in the GfdFileUploadServlet servlet allows an unauthenticated attacker |
| 19 | + to upload arbitrary files. Since the embedded tomcat application server enables auto deploy |
| 20 | + it's possible to upload a WAR file to achieve remote code execution. This module has been |
| 21 | + tested successfully on Lexmark MarkVision Enterprise 2.0 with Windows 2003 SP2. |
