Since "Anonymous" has become a well known organization, the meaning of the term also may cause confusion. In order to clarify, we correct unknown authors to simply "Unknown".

This module exploits a stack buffer overflow in the Sybase EAServer Web

Console. The offset to the SEH frame appears to change depending

on what version of Java is in use by the remote server, making this
|
|
exploit somewhat unreliable.
