|
This module exploits a stack-based buffer overflow in Beetel Connection
|
|
Manager. The vulnerability exists in the parsing of the UserName

parameter in the NetConfig.ini file.
|

|
|
The module has been tested successfully against version
|
|
PCW_BTLINDV1.0.0B04 on Windows XP SP3 and Windows 7 SP1.
