SAP default passwords are nothing new. The top five default passwords are presented in many books and articles on security issues. One would hardly find anything new on this topic.
Carrying out SAP security audit for a client, we came across an unknown password of the user TMSADM. The password was displayed by the system itself: during the default accounts analysis, the following results were obtained in the known report RSUSR003.
The default password for TMSADM — PASSWORD — really is well known, but this is the first time I have seen the password $1Pawd2&. Let's sort it out...
The first thing that comes to your mind is to search on the Internet. Google gives two references. The SAP website, six. None of them clarifies the matter: the mysterious password is mainly discovered in published fragments of the ABAP code.
Apparently, we should look for the answers in the code. We open the source code of the report RSUSR003 and have no difficulty in finding the message we've seen on the screen before (message 028).
We also find default passwords hashes that are implemented to the program source text. Interestingly enough that there are two groups of hashes for the user TMSADM: one for the password PASSWORD and another for $1Pawd2&. Here they are (they might be useful for audit, penetration testing etc.).

Now we can remember that there was no information on the transport management system user TMSADM in previous versions of the RSUSR003 report. As we can see, there's no such account in the analysis results output.
Apparently, the report has recently been revised and new versions contain information on default passwords and TMSADM password. It has been revised... And a new unknown password has appeared. Checking. Let's see the very beginning of the source code: it usually has information on updates and amendments that were made.
The very last update of the source code is related to adding user checks. For more information let's see the note (issued in a month following the code changing, on April 27, 2011).
Everything is confirmed. In early 2011, SAP developers made changes to the report RSUSR003, added checks for the user TMSADM providing two possible passwords: PASSWORD and $1Pawd2&.
Conclusions we can draw:
