|
|
This module exploits a stack-based buffer overflow vulnerability
|
|
in the web interface of DiskBoss Enterprise v7.5.12 and v7.4.28,
|
|
caused by improper bounds checking of the request path in HTTP GET
|
|
requests sent to the built-in web server. This module has been
|
|
tested successfully on Windows XP SP3 and Windows 7 SP1.
