T 5.54 Deliberately causing an Abnormal End
A Netware ABEND (Abnormal End) occurs when the Netware operating
system can no longer carry out or control network processes properly due to
hardware and/or software problems. In this case, the file server is stopped and
must be restarted.
If an attacker has access to a Novell Netware server-console, the input of
certain parameters will allow deliberate execution of an ABEND.
The abnormal end of a Novell Netware Server can even be caused by anyone
having access to the network, without an authorised login being required. By
opening the program SYS:\PUBLIC\RENDIR.EXE with additional parameters,
every workstation with an "Attached" status can provoke an ABEND on a
Novell Netware Server.
