Description

Some variants of IBM 370 may allow a malicious user to gain full administrative priveleges via the "VM Guest" account and the DIAGNOSE function. The flaw occurs due to no authentication checks applied to the account or DIAGNOSE function which is considered 'priveleged'. With this command, the local user can perform untraced and undetected I/O on the system, allowing a wide range of commands and access.
