|
This module exploits a stack buffer overflow in the MaxDB WebDBM
|
|
service. This service is included with many recent versions
|
|
of the MaxDB and SAPDB products. This particular module is
|
|
capable of exploiting Windows systems through the use of an
|
|
SEH frame overwrite. The offset to the SEH frame may change
|
|
depending on where MaxDB has been installed, this module
|
|
assumes a web root path with the same length as:
|
|
|
|
C:\Program Files\sdb\programs\web\Documents
