IBM SYSTEM I ACCESS FOR WINDOWS CODEIt converts RPG and COBOL source code to object code that runs natively on x86 virtual machines (VMs). The architecture described here uses it to migrate System i workloads to Azure. While this can be argued to be effective in stopping brute-force login attempts, it can also be argued that number is too low, effectively allowing for a trivial DoS against the system, especially given all of the potential default credentials on the system (covered by Nessus plugin ibmi_default_password.The Infinite i suite is from Microsoft partner Infinite Corporation. Note that while the CVSSv2 score for this is considered 'low risk', the immediate follow-up allows for access to an additional host, possibly with administrator privileges.īy default, IBM iSeries has a policy limiting failed logins to three. IBM SYSTEM I ACCESS FOR WINDOWS PASSWORDNessus plugin 57849 ( ibmi_cached_password.nasl) can access the registry and decode the password if the scanner is given sufficient privileges to access the registry. This poses security risks as the local administrator may not be authorized to access the iSeries host, and should not be allowed to see a domain administrator's password. IBM SYSTEM I ACCESS FOR WINDOWS WINDOWSHost:, UserID: QSECOFR, Password: more interesting, and scary, part of this is that IBM iAccess for Windows also acquires a copy of the user's Windows password, and stores it in the same insecure manner. windows, UserID: dadmin1, Password: s******e The following shows a local administrator is enable to see passwords of dadmin1 and QSECOFR: Nessus was able to extract the following cached password(s) for IBM iSeries system(s) : Any user (domain or local) having access to the registry entries where encrypted passwords are saved on dadmin1's workstation, can decrypt the passwords.She signs on with the QSECOFR account and performs tasks on the iSeries host. ![]()
