|
||||
This module exploits a vulnerability in the igssdataserver.exe component of 7-Technologies
|
||||
IGSS up to version 9.00.00 b11063. While processing a ListAll command, the application
|
||||
fails to do proper bounds checking before copying data into a small buffer on the stack.
|
||||
This causes a buffer overflow and allows to overwrite a structured exception handling record
|
||||
on the stack, allowing for unauthenticated remote code execution.
