SAP weak/predictable user credentials
Description
Exploiting weak/predictable user credentials is one of the most common and successful attack scenarios used against SAP systems. During the installation, SAP systems create the standard users SAP*, DDIC and EARLYWATCH. Invicti tried the default passwords for these standard users (and other commonly used SAP users) and managed to guess a set of credentials that were accepted by the SAP system.
Remediation
To protect standard SAP users from unauthorized use: <br/> <ul> <li>Define a new superuser and deactivate SAP*.</li> <li>Change all of the default passwords for these users.</li> </ul>
