Samba < 3.0.2 mksmbpasswd.sh Uninitialized Passwords

high Nessus Plugin ID 17722

Language:

Synopsis

The remote host might contain a flawed account management script.

Description

According to its banner, the version of Samba running on the remote host is earlier than 3.0.2. Such versions are shipped with an account creation script (mksmbpasswd.sh) that, when utilized to disable a user account, may overwrite the user's password with the contents of an uninitialized buffer. This could lead to a disabled account becoming re-enabled with an easily guessable password.

Note that Nessus has not actually tried to exploit the issue or determine if the issue has been fixed by a backported patch.

Solution

Upgrade to Samba 3.0.2 or later.
