|
|
This module exploits an SEH overflow in Konica Minolta FTP Server 1.00.
|
|
Konica Minolta FTP fails to check input size when parsing 'CWD' commands, which
|
|
leads to an SEH overflow. Konica FTP allows anonymous access by default; valid
|
|
credentials are typically unnecessary to exploit this vulnerability.
