'Description' => %q{
|
||||
Netgear's ProSafe NMS300 is a network management utility that runs on Windows systems.
|
||||
The application has a file upload vulnerability that can be exploited by an
|
||||
unauthenticated remote attacker to execute code as the SYSTEM user.
|
||||
Two servlets are vulnerable, FileUploadController (located at
|
||||
/lib-1.0/external/flash/fileUpload.do) and FileUpload2Controller (located at /fileUpload.do).
|
||||
This module exploits the latter, and has been tested with versions 1.5.0.2, 1.4.0.17 and
|
||||
1.1.0.13.
