VSS 6 admin user password cracking

 

First:

The secret is to hack the Um. dat file to remove the Admin Password

From offset 80 the bytes are (all numbers are hex)

0: 80 55 BC 7f 41 64 6D 69 6e 00 00 00 00 00 00
0: 90 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
0: A0 00 00 00 90 6e 00 00 A8 01 00 00 00 00 00 00 00

Just load the Um. dat file into a hex editor and change the bytes from =
Offset 80 to exactly what is shown above. When the sourcesafe Admin Tool =
Starts it believes that the admin password has never been set.

The hex values above are taken from a 'virgin 'Um. dat file

Of course, you didn't get this from me... and always backup first (just =
In case I'm wrong)
Explain it in Chinese:

If you forget the password, open the folder where your VSS database is located, open the data directory, and find um. DAT file, open and edit it in the hex Editor, change the value from 55 to 55 of offset 80 as described above, and then save it, so that um. the DAT file returns to the initial state (virgin? :)), Then open VSS admin and log on with the admin user. No Password is required!

 

 

 

Second:

You can change the Windows login user to admin and enter the VSS database. You will find that you do not need to enter any password at all.

 

 

 

Third:

Another way is to find a machine that has just installed the VSS server, and use the username and password file to overwrite the current directory.
