The cvs client blindly trust paths returned to it by the server. Therefore, a cvs client could be tricked into creating a file anywhere on the system by a malicious server.
|
|
|
|
This problem can be tested yourself as follows. Although this example
|
|
runs a faked cvs server using the :ext: method, this vulnerability is
|
|
available with any method (including :pserver: of course).
