COMMAND
STAC Replica
SYSTEMS AFFECTED
Win NT
PROBLEM
Steven Kastl found following. STAC International markets a
product for various OS' called Replica. It is a backup / restore
/ disaster-recovery tool. This advisory deals specifically with
the version for NT.
Problem here is that passwords are stored in clear text. With the
update to the latest version of Replica (3.05, I believe) there is
a scripting facility for creating scripts to backup systems. These
scripts are created via an application that presents the user with
a series of questions about the backup operation to be performed.
Part of this 'config' information is 'Username:' and 'Password:'
(Both username and password need to be entered twice--which makes
extraction even easier). A check of the resulting file shows it
contains the password in clear text.
SOLUTION
STAC International has been notified, but do not have any
immediate plans to correct this issue. There is little Stac can
do. This is the general problem of having a non-interactive
process access a privileges service that requires a shared secret.
Encrypting or obfuscating the password would gain little as
they would have to store the secret somewhere and their algorithm
could be reverse engineered. It is the same problem with the LSA
secrets. The only thing you can do is protect the secret with the
operating system access controls. Don't use the scripting engine
or else be *overly protective* of these files (e,g. call the files
across (via FTP) from a secure server behind a firewall to a
protected directory on the server and then execute them. Once
execution is complete, delete them).
