CVE-2012-4856


TITLE

IBM Power 5 Service Processor privilege escalation vulnerability

Trust: 0.8

sources: CERT/CC: VU#194604

DESCRIPTION

The Service Processor in the IBM Power 5 91##-### and 940#-### before SF240_418_382 does not ensure that firewall code is executed, which allows remote attackers to execute arbitrary code via unspecified vectors. IBM Server Firmware Power 5 is prone to a remote privilege-escalation vulnerability. Attackers can exploit this issue to gain unauthorized administrative access to the affected device. This may aid in further attacks
