Security Bulletin: IBM Flex System Manger expired USERID password vulnerability (CVE-2013-5424)


Vulnerability Details:

CVE ID: CVE-2013-5424.

All affected versions of the Flex System Manager (FSM) are vulnerable to allowing an attacker access the FSM without knowledge of the system-level account (commonly referred to as USERID) when the current password for this account is expired.

This vulnerability would allow the attacker to create accounts and run tasks as a rogue user. USERID and the rogue accounts will be running in the FSM restricted shell environment which blocks the access that an account has to the FSM internal functions.

This vulnerability only exists with the system-level account.
