|
||
|
|
This module exploits a stack overflow in the MaxDB WebDBM
|
||
|
|
service. By sending a specially-crafted HTTP request that contains
|
||
|
|
an overly long database name. A remote attacker could overflow a buffer
|
||
|
|
and execute arbitrary code on the system with privileges of the wahttp process.
|
||
|
|
|
||
|
|
This module has been tested against MaxDB 7.6.00.16 and MaxDB 7.6.00.27.
