|
|
This module exploits a vulnerability found in Ricoh DC's DL-10 SR10 FTP
|
|
service. By supplying a long string of data to the USER command, it is
|
|
possible to trigger a stack-based buffer overflow, which allows remote code
|
|
execution under the context of the user.
|
|
|
|
Please note that in order to trigger the vulnerability, the server must
|
|
be configured with a log file name (by default, it's disabled).
